The man and his experience of the world are within the waking or dream. Waking experience disappears as the whole in deep sleep as formless non-dual substance. ‘Ego’ or “physical self is limited only to the Waking or dream. The waking and dream are unreal on the standpoint of soul as self. Everyone experiences the duality as reality because they take the physical self to be the real self. This has to be investigated and verified to understand and assimilate the self-knowledge.
Deep sleep gives the clue to the non-dual experience in which the whole experience of duality is absent. There is no burden and bondage in deep sleep. However in waking experience the burden and bondage, sense of duality and gravity appears.
The physical self is totally absent in deep sleep. The seeker has to analyze the three states through inquiry, analysis and reasoning on the true base, to realize the fact that, the witness of the three states is formless and apart.
Whatever manifested as Waking or ‘dream will arise and subside, like a sunrise and sunset. The desultory manifestation cannot be real, therefore mind/ waking is mere illusion. Man and the world are reality within the waking experience but the waking experience itself is myth. Therefore the physical existence is myth.
The religionists and intellectuals who expound knowledge believe that the world is first and people were born in it afterwards. So long as this conviction is there, they cannot expound the self-knowledge because the waking experience itself is mirage therefore the birth, life, death and world are part of the mirage and has no value in the realm of the truth.
Only within the Waking or dream the sense of separation is experienced. Prior to appearance of the Waking experience, there was neither the person nor the world. The duality ceases to exist without the waking or dream experience. Only when the Waking or dream appears the person and the world is present. In deep sleep it has subsides and becomes one with the formless substance.
Only in Waking or dream the waking or dream entity is aware of itself and the world. Therefore, seeker has to investigate to overcome the doubts and confusion through by understanding the fact that waking or dream entity are false self within the false experience. The true self is the formless substance and witness of the three states.
