Journal of Consciousness Explorations & Research, April 2019, Vol. 10, Issue 3, pp. xxx-xxx Consciousness from the Outside-In and Inside-Out Perspective Tina Lindhard (PhD) International University of Professional Studies (IUPS), Maui, Hawaii, USA *Corresponding Author: t.lindhard@iups.edu / consol.tina@gmail.com Abstract In this paper I adopt a multidisciplinary perspective and the main aim is to increase our understanding of consciousness and to give us an overall view of this multifaceted term. I distinguish between the outside-in and inside-out methodological approach to the study of consciousness and I qualify what I mean by these two terms. The outside-in approach, including the neuroscientific method involving the study and mapping of the brain and psychological approach, which is based on observations of patients in psychotherapy, leads to theories based mainly on our senses or extensions of them and inductive and deduction reasoning. The phenomenological inside-out approach where people study the nature of their own consciousness, involves going below or above the thinking mind guided by intuition. This gives rise to theories based on intuitive insight and experience. Among other things, how different cultures view consciousness is also considered and I point out that whatever metaphysical position we take regarding the origin of consciousness will have an effect on what we consider as ethically permissible conduct in scientific explorations and experiments. Keywords: Consciousness, phenomenology, inside-out, outside-in, different cultures. 1. Introduction This article is a brief overview of Consciousness and some of the issues involved in its study. In it I briefly delineate some of the many aspects related to the concept consciousness including how consciousness is studied. Based on differences in methodology, I distinguish between the outside-in and the inside-out method and I clarify what I mean by these terms. I take a multidisciplinary perspective and the main aim of this paper is to increase our understanding and to give us an overall view of this multifaceted term. Although these days consciousness and its study is attracting much attention in the scientific world, in the West the study of consciousness is still in the infancy with very little consensus on what consciousness is and how it arises (Chalmers, 2002; Grof, 1985; Block, Flanagan, & Guzeldere, 1997; Crick, 1994; Dennett, 1991; Pribram & Ramirez, 1980; 1995; Velmans, 2009) However, even if the West does not know what consciousness is, they know a considerable amount about consciousness. To throw light on the concept of consciousness, I also consider what this term means to different cultures and I suggest there might be differences in the experiencing consciousness of males, females and children, at least at the more superficial levels. Information about the chakra system is briefly addressed as well as some of the instruments, which give a visual perspective of the light which radiates around a person and that alters according to person’s changing inner conscious state. 2. Different Aspects of Consciousness 2.1. Consciousness and our Subjective Experiences We are conscious human beings and, unless we are suffering from some sort of degenerative disease, most of us are aware of that. However, when we listen to experts talking about the topic, we may wonder what their comments have to do with our own subjective experiencing consciousness. No doubt this even creates confusion in some of us. Generally, this is positive since confusion often indicates that our old way of thinking about something is no longer valid, and it therefore encourages us to undertake a rearrangement or expansion in our ideas. However, if this rearrangement is purely on the intellectual level and goes contrary to our subjective inner experiences, then we might start a process that cuts us off from our own deeper inner wisdom. In his book, Modern Man in Search of a Soul, Jung (1933) addresses this topic and even though the book was written in 1933, the topic is as relevant today as it was then. When we deny our own inner experiencing reality and give preference to the view presented by so-called experts, we can land up feeling like a ship which is bobbing around on a vast sea not knowing which way to go. 2.2. Knowledge and Existence In physics, what is not observable or what is not known through theoretical prediction is often seen as not existing. This is one of the problems related to science, especially if we apply the same criteria to the study of consciousness. But we must remember that knowledge is not existence, but it is always partial and reductive. Aristotle ... understood the relation between ... Universals (knowledge) and ... individual concrete reality ... (where) universals are only (an) abstraction of (a) partial aspect of it. It is true that all that can be said about the physics of reality have to be said in terms of Universals, but all (that) can be said now and in the future will never be reality but only a tiny aspect of Universal nature. In a way, most of reality will never appear as physical knowledge. But theoretical existence, the existence in an abstract realm of existence is not a primary existence; it only exists as an abstraction of what exists by itself, reality. (Bassard, 2017) . 2.3. Consciousness, Science and Education In science, consciousness research mostly involves acquiring knowledge about the consciousness of other people. I refer to this method as the outside-in approach. In the West scientists, in general, do not consider information based on the researcher's inner experiences as a legitimate area of scientific study. We, therefore, have the rather peculiar situation that our direct experience is undervalued not only by the scientific community but also often by ourselves. This also arises because our educational systems are primarily about imparting and acquiring knowledge, and does not address how people can live fuller, more complete and happier lives. For example, students are taught when Columbus arrived in America, yet they are not taught how to breathe more fully so that they can feel more alive, improve their health and possibly avoid many future illnesses. Likewise, they are not taught through experimentation how their thoughts affect not only others but also themselves (Lindhard, 2015). I do not want to imply here that the teaching of knowledge is not relevant, but that education should also address the importance of our experiencing consciousness. Coming from the perspective of social work, Pulla (2017) points out the importance of empowerment, inherent strengths and humans' resilience. It is these subtle aspects that to a large extent determine our happiness, especially when facing adverse life conditions. That the world we perceive outside is related to our consciousness as held by quantum physicists, is not usually contemplated. In effect, most scientific disciplines, including our educational systems, still support the Newtonian-Cartesian paradigm which considers that reality, or the world out there, consists of material objects that are separate in space and time and are unconnected at any deeper or implicate level. According to this view, consciousness is a product of matter, and more specifically a product of the brain. In addition, the world is seen as being independent of the consciousness of the observer. Although this paradigm has been replaced in quantum physics, other disciplines still espouse the old Newtonian-Cartesian paradigm. 3. The Western Approach to Consciousness In the West, the prevailing method for studying consciousness is from the outside-in. Whether it is the neuroscientific approach, which deals with the neural system and also maps the brain, or psychological theories like that of the Freud, Jung, Adler and other theorists which are based on the insights arising from the experiences of their clients, the way of obtaining information is from the outside-in perspective. In science, information about the world is obtained via the senses, or instruments, which replace the physical senses like microscopes, electroencephalograms (EEGs) and gigantic telescopes, which explore the heavens beyond that of our normal sight. Scientific theories are often based on these observations although some scientists such as Einstein admit to role of intuition and inspiration in forming theories (Root-Bernstein & Root-Bernstein, 2010). Quantum physics has now replaced: the concept of solid, indestructible matter and separate objects and shows the universe as a complex web of events and relations . . . However, the physicist has very little to say about the variety of the different forms the cosmic dance takes on various other levels of reality. The experimental insights from unusual states of consciousness suggest the existence of intangible and unfathomable creative intelligence aware of itself that permeates all realms of reality. This approach indicates that it is pure consciousness without any specific content the represents the supreme principle of existence and the ultimate reality. From it everything in the cosmos is derived. (Grof, 1985, p. 72) This quantum model of reality has still not made its way into the life sciences. 3.1 Neuroscientific Approach to Consciousness Based on the assumption that consciousness is connected with the brain, neuroscientific research is primarily geared around mapping the brain and also establishing how the brain works. This has given rise to a variety of theories about how the brain functions. To name just a few, Crick and Kocj's (1990) theory centers about oscillations in the cerebral cortex; whereas combining quantum mechanics and neuroscience, Hameroff and Penrose's (2014) theory, known as the "orchestrated objective reduction" ('Orch OR') theory, is derived from quantum vibrations in microtubules, protein polymers inside brain neurons which is combined with the idea that consciousness has been ever present. Fisher (2015) also combines quantum mechanics and neuroscience but his theory suggests that nuclear spins of phosphorus atoms serve as rudimentary quibits in the brain - which enable the brain to act like a quantum computer. This has a certain resonance with Hu and Wu's (2004) earlier "spinmediated consciousness theory" where the possible roles of neural membrane nuclear spin ensembles and paramagnetic oxygen are considered. According to the philosopher Chalmers (1995) these theories address the easy task of consciousness, because they are concerned with objective mechanisms of the cognitive system. However, they do not deal with the hard part which involves explaining how neural brain processes give rise "to subjective experience … the way things feel for the subject" (Chalmers, 1995, p. 81). 3.2 Psychological Theories Although Freud was not the first to use the term the unconscious, he was the first in the West to put forward a psychological theory involving the conscious, preconscious and unconscious mind. His theory arose out of attending his clients who had psychological problems using an approach, which became known as Psychoanalysis (1915; 1920). To these categories of mind, his pupil Jung added the idea of the collective unconscious, and in this way distinguished between the personal unconscious involving issues pertaining to the person and the collective unconscious, which, for him (1997) was primary. For Jung, the human collective unconscious is populated by instincts and archetypes or universal symbols such as the Great Mother, the Wise Old Man and the Shadow. The "collective unconscious does not develop individually but is inherited. It consists of pre-existent forms, the archetypes, which can only become conscious secondarily and which give definite form to certain psychic contents" (Jung, 1997, p. 43). Although there are many theorists, the next and last I consider is that of Adler. His approach is known as Individual Psychology and it stems from the Latin term individuus meaning indivisibility, a term intended to emphasize holism. Adler (1981 ed.) included the importance of the social relationship and the community in conjunction with depth psychology, which for him incorporated an unknown goal-directed creative force. 3.3. Natural Philosophy, Science and Philosophy In the West, the questions about the nature of nature gave rise to a field that from the time of Aristotle up to the 19th century was known as natural philosophy. This term eventually gave way to the word science, which was coined by Whewell in 1833. The shift was not only in the word but was accompanied a change in emphasis from natural science to empirical science where experimental science and the scientific method became a specialized branch of science apart from that of natural philosophy. The breakdown of natural science into different fields and disciplines, such as physics, biology, mathematics etc. also came about with this shift in emphasis. Some Philosophers in the German tradition such as Goethe were uncomfortable with the application of the Newtonian reductive method of science and its philosophical underpinning to nature (Goethe, 1810; Zajonc, 1976). For Goethe, it created a split between what is observed and the essence behind what is observed. Hegel and Schelling also formed part of this movement, which was known as Naturphilosophie (philosophy of nature). What united these philosophers were their attempts to unify nature and spirit. Today the analytical, reductive perspective prevails in the life sciences and biological systems are seen as either being constituted by nothing but molecules and their interactions or that biological process are identical to some particular physiochemical process. The latter type of reductionism is sometimes considered as being only metaphysically identical, making this position less extreme (Brigandt & Love, 2017). Analytic approaches to biological systems also look at the different elements in isolation without taking the bigger picture into account. 3.4. The Western Phenomenological Perspective In early nineteen hundred, Edward Husserl founded the phenomenological movement in the West. In a way, his concept of phenomenological reductionism pre-empted the view of quantum physics by providing a new epistemology through which the quantum vision could be matched (Lattuanda, n.d.). Husserl felt that taking outward reality as "a priori true and extant," "was naive and uncritical" (Lattuanda, n.d., p. 17). As such he, like Plato, placed philosophical inquiry as being higher than scientific investigation. From the perspective of phenomenological analysis, the concept of bracketing (or epoché) involves the suspense of all judgments about an object's physical or objective nature, as the only reality is what appears to the mind (Farina, 2014). According to Lattuanda (n.d.) true knowledge for Husserl arises from a philosophical investigation where all judgments are withheld or bracketed except that of consciousness itself (p. 17). However, an exact definition of phenomenology and the process is not so easy as Husserl himself, and his students who followed him, adapted it in different ways giving rise to significant differences in what is involved in the term. Farina (2014) classifies phenomenology as "a method" or a "style of thought" rather than a "doctrine "or "philosophical school" which gives rise to "every renewed experience having different results" (p. 50). Husserl's method is an example of an inside-out position but varies slightly from the Eastern approach described below. 4. The Eastern Approach to Consciousness In the East, the phenomenological perspective or the inside-out approach has always been the prevalent way of obtaining information. Using inner inquiry as a method, they have studied the nature of consciousness and any other topics of interest for thousands of years. Interestingly, both the Eastern inner scientist and the Western scientist of the outer world, start their inquiry from the same questions arising out of their wonder about the world and the cosmos in which they find themselves living. In ancient times this gave rise to questions such as: Who am I? How does Nature work? How do I fit into all this? How does the physical Universe work? What if anything, is behind Nature? These inquirers then sat down and took these questions deep inside themselves and waited for intuitive answers to arrive. These inner explorers also felt that if they could discover their own nature, they would know the nature of the Universe (Arka, 2013). They become known as philosophers, seers, yogis and rishis. In India the insights of these early inner explorers were recorded in ancient texts known as the Vedas, meaning knowledge or wisdom. The Vedas and some of the texts that are commentaries on the original verses are considered as Sruti or Shruti (Lochtefeld, 2002). This implies that the information the texts contain is based on information that is "heard" rather than Smriti (Editors of Encyclopaedia Britannica, n.d.) or information that is 'remembered’. Although the Vedas are said to date back to 1700-1100BC, their contents reveal that the information they contain has been passed down verbally for thousands of years with the Rig Veda possibly dating as far back as 8000 BC and 6000 BC (Priyadarshi, 2014). 4.1. Meditation and Inner Experiences It is not so easy to turn one´s attention inward. For this reason, yogis developed methods of meditation to help people in this task. The methods themselves are not meditation but give rise to experiences and intuitive insights. The most researched method in the West is called Mindfulness. The modern version of this is related to complete attention while undertaking any activity but the original method is a Buddhist based practice, which is related to the nature of mind. There are many other methods, including those that involve somatic focusing. The oldest somatic focusing method is referred to as Prayer of the Heart and it was known to the ancient Egyptians, Jews and other Mediterranean cultures as well as being the method practiced by the Desert Fathers in the early Christian tradition. It is also close to the traditions involving Self-enquiry (atma-vichara) and Kashmiri Shaivism as well as the Sufi tradition (Louchakova, 2004). The core of these practices is ego transcendence, and contemplation of the Self is the "experimental phenomenological introspection into the living topological construct of the Self " (Louchakova, 2007, p. 82). Through the cultivation of inner silence (heshychia in Greek), the practitioner goes through several stages leading to the state of Theosis ie Union with God (Louchakova, 2006; Louchakova, 2007). A new somatic meditation method, known as Intuitive Meditation (IM) or Arka Dhyana (Arka, 2013) avoids some of the complexities Louchakova (2007) associates with Prayer of the Heart. IM is based on three main pillars: touch, sound and breath, and with these, the practitioner directs and trains his or her attention to go to different parts of the body. Via this practice, the person can experience his or her conscious awareness in different energetic centers of the body, as well as learn how to live from the state of Conscious Awareness with full involvement of the heart. This method is connected to Arka's (2013) Theory of the Six Main Levels of Consciousness, where the practitioner is said to experience the different levels as he or she descends from thinking mind consciousness to a heart-based feeling mind conscious and beyond. The main levels are: 1) M (Mind) – Consciousness, 2) SM (Subliminal-Mind) – Consciousness, 3) F (Feeling-Mind) – Consciousness, 4) H (Emotional- Heart) – Consciousness, 5) HS (Heart-Soul) – Consciousness and 6) PS (Pure-Self) – Consciousness (Arka, 2013). A recent exploratory study by Lindhard (2017; 2018a) has shown that practitioners experience a different quality in their consciousness after learning the IM method and practicing it for a minimum of 13.5 hours over six weeks. Armour's research (1991, 2007, 2008) supports the hypothesis of a brain of the heart, which allows it heart to act independently of the brain, sending and receiving meaningful messages of its own through the autonomic nervous system. McCraty (2009) has also shown that more information flows from the heart to the brain than from the brain to the heart. Arka's theory (2013), accounts based on the Prayer of the Heart method (Louchakova, 2006; 2007) and the Intuitive Meditation method (Lindhard, 2017; 2018b) and these above-mentioned studies suggest that the heart might play a bigger role in consciousness that is presently recognized by mainstream science. 5. Anthropology, Consciousness and Spirituality By now our readers would have become aware that consciousness is a vast topic that embraces many different aspects. If we do not consider it from an anthropological perspective, we would not be doing justice to the many traditions on this earth who essentially managed to live a life in harmony with Spirit, Nature and the environment. In the Native American tradition, storytelling was used to instill respect for Nature in the consciousness of the younger members of the tribe. Although they did not vocalize their spirituality in the same way as the Indian tradition, their stories bear witness to their inherent comprehension regarding the spiritual nature of the Universe in spite of the fact they did not use the term consciousness (Honeycutt, 2018). Other communities throughout the history have also borne witness to the inherent spiritual nature of the Universe and their understanding of well-being, happiness and peace are linked to this. 5.1. Beyond the World of Matter Although most Western scientists are concerned with understanding the world of matter, it would be incorrect if we assume that all Western Scientists were or are not interested in what is behind matter. The world-renowned scientist Max Plank stated: As a man who has devoted his whole life to the clearest-headed science, to the study of matter, I can tell you as a result of my research about atoms this much: There is no matter as such. All matter originates and exists only by virtue of a force, which brings the particle of an atom to vibration and holds this most minute solar system of the atom together. We must assume behind this force the existence of a conscious and intelligent mind. This mind is the matrix of all matter. (Planck, 1944) 5.2. Indian Spirituality The statement of Planck is consistent with Indian spirituality where there is "one supreme intelligent force, hitherto unknown, that encompasses all the forces we know today. It divides into various forces and sub-forces to govern itself and creation. This does not happen just once or twice: it is an ever-blossoming flower of creation that will never cease or fade (Arka 2003, p. 174). This means that wherever we look we will find "consciousness", it is imminent in all creation and it, of course, is in us. In the Rigveda they talk of "the ONE BEING the wise diversely speak of. Ekam Sat-Viprah Bahudha Vadanti. According to Arka (2003): There is a strong, inseparable connection between human existence, human consciousness and consciousness in the cosmos; the whole living body is like a fruit of nature. If we study a fruit, we can extrapolate its root source, its region of origin and the conditions of its planting or harvesting. Similarly, the fruit of the physical body with a conscious spirit within has the potential to understand, experience and connect with its source in the cosmos. (Arka 2003, p. 66) The nature of pure consciousness in the Indian Vedic tradition is referred to as SatChitAnanda, pure Being, pure Knowing, and pure Bliss (Encyclopedia of Hinduism) and there are three fundamental philosophical positions one can adopt regarding this supreme intelligent force. They are known as Dvaita, Advaita and Vishistadvaita. According to Dvaita, "all living entities and the universe are separate from the higher being (God)"; Advaita maintains that "all forms in the Universe are unreal (and) only pure individual consciousness is real" and Vishistadvaita "propounds that souls and the universe full of matter are all real and Brahma's manifestation." Followers of this last mentioned school of thought, do not want to merge with Vishnu but continue to be in "close enjoying adorations and bhakti" (Arka, 2018, p. 105). What distinguishes Buddhist philosophy from Indian philosophy is that Buddhists do not believe there is a soul or Self (Buddha, n.d.; Ruparell & Markham, 2001). 5.3. Consciousness, Metaphysics and Ethics One's ethical stance ultimately depends on one's metaphysical position regarding the nature of consciousness. In embryological research, for example, what one considers as ethical behavior will be conditioned by one´s stance on the bigger picture. Is the embryo just a heap of cells or matter which gives rise to consciousness, or is consciousness primary? In other words, is consciousness the property of soul; is it the property of matter or is it Spirit consciousness manifesting itself through matter? Obviously how one answers these questions has implications when considering modern in vitro fertilization (IVF) methods, including the method known as Intracytoplasmic sperm injection (ICSI). If matter is a product of consciousness, we also have to ask ourselves when does soul descend into matter? This too will have implications on how we treat zygotes, which during artificial insemination are often frozen, sometimes for years. Some consider a zygote as just a fertilized egg; others view it as a living organism. 5.4. Near Death Experiences It seems that at either extreme of human life is when these questions become more pertinent and relevant and may be possible to answer. Near death experiences (NDE) are another area where scientists are trying to find out if something exists beyond that of the material body. In people who have undergone a NDE, researchers who are often the medical professionals themselves, have found that in spite of showing no brain or heart activity, these individuals report of having conscious experiences during the period when officially they were considered as being dead (Moody, 2001; van Lommel, 2006: Holden, Greyson & James, Ed., 2009). When comparing the experiences of different individuals, many of them show similarities in content. These experiences are similar to this reported in spiritual awakening and the rising of the kundalini (Greyson, 1993). 5.5. Wellness, Health and Dis-Ease Western man has developed an allopathic model of treating ‘dis-ease’, which is based on a chemical, biochemical and surgical approach. Treatment is designed around reducing symptoms either through drugs, surgery or massage. The approach is basically mechanistic in that the phenomenon of life is seen as being based on the same physical and chemical laws, which operate in the inorganic world. This is very different from the holistic approach originally practiced by Hippocrates where the person is immersed in a healing environment with the aim of restoring harmony and balance (Yapliakis, 2009). He believed that diseases stemmed from natural rather than supernatural causes and they could be systematically studied, treated in prescribed ways, and possibly cured according to the workings of nature (Garrison, 1966). The sufferer would descend into the womb of Mother Earth, into the abaton or small chamber in the Asklepia, thus further removed from all outside forces, and wait until the god came in a healing dream or pointed to the cure, which often included "…incubation, the application of ointments, and the use of incantations" (Tick, 2001). In the medical model the accent is on intervention, whereas the holistic approach stresses prevention. The holistic approach also takes into account the whole individual including mind, body and spirit and includes the individual's responsibility for his or her wellbeing as well as social, psychological and environmental influences. This may also include aspects such as nutrition, exercise and mental relaxation (Allison, 1998). These aspects can be seen as ways to help change the state of consciousness of the suffering individual and serve to restore his or her state of health and harmony both inside and outside. The Western mechanistic approach is relatively new in the history of man and thousands of techniques predate this tendency (Streeter, 2014), which are based on subtle energy, like the chakra system. Acupuncture is an ancient system based on the movement of life in the organism, as is the Ayurveda system. Harmony and balance are seen as an integral part of all holistic medicine. Each part, including the person's consciousness, is also seen to affect and be affected by every other part and yet the whole is seen as being greater than the sum of the parts. Once again in this, we find a pointer to a mystery, which lies beyond and behind the manifest Universe. 5.5.1. The Chakra System In discussing models of consciousness, it is necessary to talk about the chakra system. Simply put, it is the subtle energy system of the body where each chakra, meaning wheel in Sanskrit, is said to “animate each person´s physical, mental, emotional and spiritual body. The idea of the chakra system entered India´s sacred texts between 1800 and 800 B.C" (Beshara, 2013 p.30). This system has also become increasingly used or adapted in the West by various Western theorists among others Jung, Maslow, Wilber, Myss, Ruumet, and Leary. The seven major chakras are seen as being situated along the vertebral column and the following attributes are said to be associated with each of them. The base Chakra (Muladhara Chakra) is to do with the material world, survival and being grounded. The Sacral Chakra (Swadhistana Chakra) is to do with sexuality, work, physical desire, our connection with others and our ability to accept new experiences. Solar Plexus Chakra (Manipura Chakra) is to do with ego, self-worth and the ability to be confident and in control of our lives. It includes issues of power. The Heart Chakra (Anahata Chakra) is about peace and our ability to love and be loved and forgive. The Throat Chakra (Vishudda Chakra) concerns our will, our ability to communicate, which includes self-expression. The Third Eye Chakra (Ajna Chakra) is about our capacity to see clearly based on wisdom of the bigger picture and intuition. The Crown Chakra (Sahasrara Chakra) is about full spiritual connection and the experience of bliss. (Myss, 1996) 5.5.2. Measuring the Human Energy Field Sensitive instruments have been developed in the last couple of decades to measure and detect the minute energy field around the human body. These have radically changed science´s skepticism about the existence of this field from disbelief to certainty in their existence (Streeter, 2014). It has long been known that activities of cells and tissues generate electrical fields that can be detected on the surface of the skin. But the laws of physics demand that any electrical current generates a corresponding magnetic field in the surrounding space. Since these fields were too tiny to detect, biologists assumed they could have no physiological significance (Oschman & Oschman, n.d. para 7). Long ahead of his time, Burr, a researcher from Yale in the 1920s and 1930s, suggested that diseases could be detected in the energy field of the body before physical symptoms appeared and that the diseases could be prevented by altering the energy field (Matthews, 2007). The Kirlian camera, developed by Semyon Kirlian in Russia in 1939, was the first instrument to throw light on the human energy field. Today we have various means of measuring the human energy field, which includes the SQUID, the GVD (Gas Discharge Visualization Camera), which is a modern version of the Kirlian camera, and the PIP (Polycontrast Interference Photography). The latter provides a real-time, moving image of the energy field where imbalances can be seen prior to them manifesting in the physical body (Oldfield, n.d.). The person can then be treated by energy medicine. These different instruments study consciousness from the outside-in and can be used to test or shed light on different theories related to consciousness, and also reveal where the imbalances in the person's energy field are occurring. 5.6. The Effect of Sound on Consciousness It has long been known that sound vibration affects peoples’ experiencing consciousness. The film industry is well aware of this and music is used to create certain emotional effects in the audience. Throughout history, spiritual traditions have used sound "as a vehicle for introspection, spiritual growth, and the exploration of consciousness" (Otero & Muesham, 2018, Abstract). When sound vibrations make contact physically through the body, they can have "an effect on our consciousness at the mental, emotional and spiritual levels" (Ragu, 2018). Musical notes can increase or decrease in the order of pitch and the interval between notes can give rise to consonance and dissonance. Consonant intervals have been found to "cause happiness, joy, courage or calmness, dissonant intervals can cause tension, anger, fear or sadness, thereby affecting the emotional aspect of consciousness" (Raghu, 2018, abstract, p. 75). 5.7. Sleep, Brain Waves, Dreams, Meditation and Psi Other main areas of Consciousness research involve research into sleep, dreams, meditation, and drugs. Sleep is studied from the outside-in position and dreams have been found to occur during the phase of rapid eye movement (REM). This was established through observation and then waking up the sleeper when REM occurred and asking him or her what was happening. However, science cannot tell us what, if anything, dreams mean to the person as that is his or her personal domain. Science has been able to ascertain that different brain waves are related to different conscious states. In a nutshell, beta is related to waking active aroused consciousness and alpha to nonarousal. Theta is slower and it is in this state where the person often receives ideas of inspiration. It is also when REM states and dreaming occur. Delta is slower still and is related to deep sleep (Herrmann, 1997). Studies into meditation have found the brain wave activity of meditators is different to nonmeditators. Essentially, they show more alpha and theta activity (Cahn & Polich, 2006). Different meditation methods have different aims and objectives. It would also be beneficial to find out if and what differences exist between these different methods. For example, it might be interesting to find out the differences if any, between people who meditate on the deeper Self via the heart, and those that do not. Shamanistic cultures of South America go about expanding people consciousness in different ways than those used in the Indian meditative traditions. Additionally, shamans occasionally utilize consciousness-altering drugs such as Ayahuasca. Its chemical properties have been studied by scientists Callaway, McKenna, Grob et al (1999) and its use is sometimes linked with spiritual awakening (Campos, 2011). This topic is too complex to explore here, as are the pros and cons of using drugs to expand one´s consciousness. 5.8. Consciousness and Parapsychology Psi or Parapsychology is an area that captures the interest of the public and many scientists although it is not an area that is normally published in mainstream journals. It also depends on whom you talk regards whether scientists feel there is overwhelming evidence in its favor or not. Psi includes telepathy, interspecies communication, precognition, clairvoyance, psychokinesis, near-death experiences, reincarnation, apparitional experiences and other paranormal claims. The present-day researcher Radin (2006; 2013) has conducted extensive investigations into supernatural states. But this topic is also too vast to address here. However, it certainly is an area that needs to be further researched and entertained by mainstream scientists if we are to better understand the capacity of human consciousness. 5.9. Consciousness of the Different Genders and Children Another under researched area concerns gender differences. How do we know the everyday experiencing consciousness of women is similar to that of men? In psychology, men have written most of the theories of consciousness. The map, however, is not the territory. Descartes statement, I think therefore I am, does not necessarily hold true for all human beings during all stages of their lives. Maybe feeling is ontologically prior to thinking as suggested by The Theory of the Six Main Levels of Consciousness (Arka, 2013, Lindhard, 2017, 2018a). In animal experiments where much information is then generalized to humans, females are not usually used, as the information obtained when employing them is not consistent due to oscillations in hormones. Might not the same oscillations create differences in experiencing consciousness in women? Investigations into the consciousness of children from Tribal areas in India who have not been influenced by Western education indicate that they are highly creative and exploratory in their activities and they educate or learn by themselves (Kodapully, n.d.). These reflections raise questions such as what do we really know about the subjective nature of consciousness? What do we know of the experiencing consciousness of men, women, children, a new born baby, an embryo or an even an animal or a plant? 6. Summing up The fundamental problem of consciousness seems to be related to the question who are we? How we answer this will decide if consciousness is a property of matter, the ground of all existence, or the soul or a timeless conscious Mind or Spirit manifesting itself through matter. It seems that the only way to answer this is through personal inner investigation otherwise we will be relying on what others tell us or on belief. The issues and problems pointed to in this article raise many questions. Consciousness is a vast topic, which Western Science does not have all the answers. Different cultures have approached the subject of consciousness from different angles and used different methods to train their young to live in harmony with Nature, with others and themselves. Consciousness embraces every aspect of our existence and every field and it is hoped that this introduction will give the readers much on which to reflect. I also hope that these reflections into the nature of consciousness and the main ways it has been researched, will promote a deeper understanding of the term by both scientists and public alike. The outside in is only one way to study consciousness. This author personally feels the next burst in science will come when more scientists start investigating the nature of their own consciousness from the inside. As consciousness is life, we can only know about life from those who are investigating it for themselves, especially when it comes to the full range of human possibilities and capabilities. That we all do not share the same capabilities does not mean they do not exist. This applies to the ability to do algebra or a parapsychological activity; we all might have the potential but maybe we have not developed it (Radin, 2018, unpublished comment, Sadhu Sanga). I also feel that when the Eastern phenomenological approach or inside-out approach, which gives rise to insights regarding our nature and the nature of Nature, is combined with the Western disciplined approach to testing hypotheses, it will raise our consciousness awareness about consciousness. This increase in awareness will not only be about many different facets of human nature, consciousness and existence, but hopefully also the nature of Nature itself.
