Man has been conditioned to think and be and behave and believe and live as an individual separate from the world

Man has been conditioned to think and be and behave and believe and live as an individual separate from the world. Therefore, the self has been identified with physical body with the name within the waking experience.

The ‘mind’ is the Waking or dream experience. The Waking or dream is not the experience of the physical body but of the  formless Soul or consciousness, the innermost Self. The man and his world are within the mind; therefore mind is not within the brain. This has to be understood to assimilate the self-knowledge. Without understanding this fact the assimilation is impossibility.  

The nature of the soul ,  innermost self  Self is formless non-dual.  The nature of the mind is duality or diversity. The self is the formless substance of the mind (duality  or diversity). Therefore, the whole experience of the diversity created out of single stuff.  that single stuff is consciousness(soul).  Therefore, there is no division in consciousness from   ultimate standpoint . Viewing the three states  on the base of the physical self(ego or waking entity)  is the cause of division and separation.  

  When the seekers realizes the fact that ,  self is not physical but the soul, he becomes aware of the fact that,  the mind, which is present in the form of  universe  is mere illusion.   The one who is ignorant of the formless soul or consciousness, the  innermost self experiences the duality(waking)  as reality.
