The individual experiences experienced as a person of the world is happening within the waking are ultimately unreal because from the ultimate standpoint the waking experience is unreal. The entire expanse of things of things are mere mirage” analogous to a dream.
The waking experience is reality only on the base of false self(ego or waking entity) but the false self exists within the false experience(waking) . The truth cannot be got on the false base because the truth is beyond the false experience. The false self is the product of ignorance. Due to ignorance the illusion is experienced as reality.
Due to ignorance without being aware of the fact that, the true self is consciousness when one considers the self as physical then the mirage effect superimposes on the consciousness. Thus the consciousness is hidden within the mirage. Until this mirage is identified as mirage the ultimate truth will not be revealed. The ultimate truth is consciousness, and three states are product of ignorance.
The freedom is brought about by the removal of ignorance one’s perception. The wisdom arises when destruction of the ignorance by learning to view and judge and conclude the truth on the base of the soul, the innermost self. The soul is in the form of consciousness. Once the one becomes aware of the fact that, the soul,which is present in the form of consciousness is the true self then the superimposed mirage will not prevail as reality.
By deeper self search one becomes aware of the inner core, which is consciousness, as it really is. Once one becomes aware of consciousness as it is mentally, then he will see the universe ,which is in the form of mind for what it is , because the mind or universe are mere mirage created out of consciousness. The mind (universe) and the soul (consciousness) are one in essence. Thus there is unity in diversity.
Thus, the birth, life and death, which are mere happenings within the universe is illusion because the universe, which is in the form of mind, itself is mere illusion. The illusion appears as waking or dream(duality) and disappears as deep sleep(non-duality). Thus the formless substance and witness of the illusion is consciousness. And consciousness is ultimate reality or Brahman or God.
Wisdom makes it possible to free the soul, the innermost self, from illusion in the midst of illusion. In such case the physical death is merely the consummation of a process within the illusion.
The non-dualistic or Advaitic truth realized through wisdom where the mind (body, ego and world) completely become one with the source from where it rises and subsides. Thus, other than soul or consciousness everything else is falsehood. The individuality is reality within the mind (universe or waking) . When the mind (universe or waking) merges into consciousness, then no second thing exist, other than consciousness. Thus, consciousness is ultimate truth.
To say consciousness is part of the individuality is wrong because the body and the universe are created out of consciousness. The soul or consciousness has no parts because it is formless. Consciously the mind (universe)becoming identical with the consciousness is freedom or release.
