One doubt that keeps propping up again and again and that is: How the consciousness, becomes the universe?  To get the answer to this question one has first know:-

v  “What is the ‘I’?” 

v  “What is mind?”

v  “What is the substance of the mind?”

v  “What is the source of the mind? “

The  Atman ,which is in the form of Consciousness (non-duality) becomes the mind, is in the form of the universe and  the universe appears as waking or dream (duality)  and disappears as deep sleep (non-duality).  Thus the appearance as waking or dream and disappearance as deep sleep is consciousness. The one that becomes duality and non-duality is single formless stuff that is consciousness.  By knowing that stuff in the midst of duality (waking) by tracing its source, the waking entity, which is seeking the truth of its true existence, will realize the fact that, it is not the true self but the formless substance and the witness of the three states is the true self.  The formless substance and witness of the three states are one in essence. And that essence is consciousness.  Thus consciousness is the true self and ultimate truth or Brahman.
