To sleep is to surrender to the true self, which is the invisible substance and witness of the experience of duality. The sleep gives the non-dual experience or experience-less state. Sleep is an inescapable need. There is no substitute for it.
All the three states being one of the most significant phenomena in the existence of the individual must be thoroughly analyzed and understood to unfold the mystery of the mind.
Any attempts to give an explanation of three states in purely psychological terms will be incomplete and misleading as well. Everyone consider the three states to be inevitably experience of the physical entity. And psychological inventions are based on physical self and they cannot transport the seeker beyond the physical barrier.
Scientists are searching the truth within the physical body, but they fail to understand they have to investigate the mind has to exist prior to the body, because a body cannot function on its own. From where they can get the mind, which does not exist in the physical body, but pervades the whole experience of diversity. Therefore there is no way scientist can find the truth in laboratory inventions. The truth has to be got through deeper inquiry, reasoning and analysis on the true base. Thus until and unless the worldview is viewed and judged on the true base the truth will not be revealed.
Many authorities regard the three states as individual experience, and consider consciousness is the result of activating physical apparatus alone through external stimuli. The three states, in their opinion, is therefore a individual experience.
The essence of all these physiological explanation is that three states are of the physical body. This is radically wrong conclusion. A more profound investigation is required to unfold the mystery of the mind to realize the inner realities.
History speaks throughout the investigation in the past man limits his mind to physical apparatus is the main hurdle in pursuit of truth. Therefore it is necessary for the seeker of truth to investigate what is mind, before indulging in pursuit of truth. Throughout the history one is conditioned to view and judge the worldview on the physical form as self, but self is prior the physical body and its experience of the world. Thus viewing and judging the truth on the base of physical form as self is erroneous. To get the truth of one’s own existence it is right thing to view and judge the worldview on the formless entity, which is solely responsible for the existence of the experience of diversity.
The individualized viewing and judging the worldview is the hindrance in realizing the truth which lies beyond the mind. The experience of diversity [I] disappears and reappears, but one is one is aware of appearance and disappearance of the three state in succession only in the waking experience. In dream there is unawareness of the waking experience. And in deep sleep there in unawareness of the waking and dream experiences. Thus one which is aware of these three states has to be present in all the three states. Therefore it has to be something which is apart from these thee states. Thus the invisible witness [knower] of these three states has to be traced mentally and grasped. This invisible witness itself is the true self. This invisible substance and witness is present as invisible substance of the three states.
Only when the witness is traced and realized as true self, the ignorance vanishes. When the ignorance vanishes the duality vanishes. When the duality vanishes the experience of diversity is mere mirage.
The experience of diversity also evolves as self unfolds, the self becomes aware of its formless nondual nature and remain conscious of its true nature even in midst of the experience of diversity. Remaining conscious of it true nature in the midst of the experience of diversity is wisdom.
Self knowledge or Brahma Gnana or Atma Gnana is not merge in the nature and remaining in non duality. But in the midst of the experience of diversity being aware of the true self and realizing the fact that experience of diversity is mere mirage. Self is not a coincidental product of physiological process, but the very reason for the existence of experience of diversity.
Self is the standard by which the distinction between the three states should be understood. In experience of diversity [waking or dream] the person becomes conscious of him-self and perceives the world. In sleep the experience of diversity disappears.
Physiologically, the three states may be described as retarding and accelerating of higher brain centers, but they are more significantly defined as the submerging and emerging of the true self. In order to answer the basic question of why the self should oscillate between the quiescent state of sleep and active state of experience of diversity (Waking and dream),one must attack the primary origin of the mind(I or experience of diversity). Before the beginning of all the beginning, the state of formless and non-dual, the oblivion of the experience of diversity. Thus one easily conclude that, the one which is aware of its non-dual true nature and one is which is in oblivion of experience of diversity is formless entity. Thus it is necessary to seek truth on the base of formless entity in order to unfold the mystery of the mind or ‘I’.
The utter and unrelieved oblivion of self forgetfulness the non-dual nature of self beyond state was broken in order that the self should consciously know itself, in the midst of the experience of diversity.
When the self remains in its non-dual true nature it is temporarily is free from the experience of diversity, which is identified as deep sleep. Because of the compulsion of conditioned mind set prevents man from grasping the truth of the reality of his own existence and subject him to increasing limitations and helplessness. Man is a spider caught in the web of duality due to the ignorance of the true self.
In the deep sleep state self becomes latent temporarily. Until one becomes aware of the true self consciously in the midst of the experience of diversity or death, the burden and bondage of experience of diversity is bound to be there. Becoming aware of the self in the midst of experience of diversity is self realization. And knowledge of the true self is self –knowledge.
The conditioned mind set forces one to believe ‘I’ as true self, and remain in intoxication of the ‘I’ and waste the whole life time believing the ‘I’ as self. And all his seeking and practices is focused to free the ‘I’ from the experience of duality. How one can become free from experience of diversity (duality) when ‘I’ itself is the cause of duality. Without the ‘I’ there is no experience of duality. ‘I’, which appears and disappears, is causing the duality. Therefore it is erroneous to seek truth on base of ‘I’ which is not the self. Therefore it is necessary to know “What is ‘I’”, before indulging in the pursuit of truth.
In his desperate attempts during the Waking experience to overcome the duality, man attempt to escape himself through existing mindset. Although drowning himself in experiencing, the experience of diversity as reality and trying to get solace from religious and yogic and other theoretical methods which frees him temporarily, but he will nor escape from the burden and bondage of the experience of diversity, until and unless he becomes aware of the true fact that ‘I’ is not the self but ‘I’ is the whole experience of diversity. The whole experience of diversity in turn is mind. Thus it is necessary to understand the fact that mind is not limited to the physical entity, but mind is the whole experience of diversity. The invisible witness, which witnesses the appearance of disappearance of the ‘I’ is the true self. Therefore it is necessary to view and judge the worldview on the base the invisible witness in order to unfold the mystery of the mind.
As a man one identifies waking, dream and deep sleep states as human experience. But on the standpoint of the true self, all the three states are mere illusion. Until man becomes aware of the true- self ,he is bound to believe the three states as reality, and view and judge the worldview, on the base of ‘I’ as self. The ‘I’ disappears only when one views and judges the worldview on the base of true self.
When one seeks freedom from the ennul of the waking experience by loosing consciousness in the deep sleep experience, no slightest destruction of awareness occurs. Deep sleep is an experience-less awareness. Experience-less awareness is true nature of the self. Therefore consciously remaining in experience-less awareness by realizing the experience of diversity is mere mirage in the midst of experience of diversity will lead to awareness of the true self or Atman.
Deep-sleep is unconscious self awareness. To become aware of the true self it is possible only in Waking experience. Since only in waking one can speak of the deep sleep and dream experiences. Only in waking experience the aspirant is able to find and realize the true self consciously.
Deep sleep is an unconscious withdrawal of the self, from experience of diversity into temporary oblivion. In this mind (I) is completely absent. And it is in the state of burden-less and bondage-less existence. That is free from birth, life and death or pleasure and pain. Deep Sleep is unconscious stillness of the mind (I). Consciously remaining stillness within the experience of diversity is possible only when one has the knowledge of the true self. When the self is conscious of itself the experience of diversity is mere mirage and it will be able to remain as witness of the mirage.
In deep sleep both the dual and non-dual experience is forgotten as self remains as mere witness of the appearance and disappearance of the three states. In deep sleep the true self exists as merely as a witness of the dual and non-dual experiences.
