Memories are part of the illusion.

Memories are part of the illusion. All the memories are reality within the waking experience. The waking experience is unreal on the standpoint of the soul, which is the true self.  Memories are based on the individual and individuality is falsehood.  Basing the judgment on the memories will keeps one in the grip of duality. Duality is cause of ignorance and ignorance is the cause of experience the illusion as reality.  Memories of the past are part of the illusion. Without the physical self(ego)  the memories are non-existent.

Memories of form, time and space are reality within the illusion. They become unreal on the standpoint of the soul, which is the true self. All the memories of the waking experience disappear in deep sleep.  Memories of The dream experience and deep sleep experience are present in the waking experience.  When all the three states are unreal on the base of the soul, which is the true self, then what is it that is aware of the coming and going of the three states in succession?    

The one which is aware of the three states is not physical but it is the formless soul OR consciousness  or spirit.  Therefore it is necessary to grasp the existence of the formless witness in order to realize the true self is formless, which is the cause of the memories of the three states.  There is neither the three states nor the witness exists in reality. Therefore, there is a need to bifurcate the witness from the illusion by realizing the witness and the illusion are one in essence.  Therefore, there is no second thing exists other then the soul or consciousness or spirit, because the whole experience of diversity is created out single stuff, that is the soul or consciousness or spirit. When the soul becomes self-conscious then the duality will vanishes as non-duality.
