Consciously becoming aware of the soul or consciousness in the midst of the waking experience is non dual Self-Awareness.

Anyone puts their hand in fire it is the universal experience that the nature of the fire is hot, and that even if a man says it is cold, the fact of heat remains. Same way the one who is aware of the three states in waking is aware of the awareness of the three states.

The "three states" is the totality of man's experience, which gives one the dual and non dual experiences. Waking experience is converted into idea. People do not want to go deeper.  They do not want to know what an idea is. Where has the deep sleep gone? It disappears as Consciousness when waking takes place.  The whole experience of diversity (waking experience) disappears as Consciousness. That is the point. That Consciousness is what the seeker of truth has to get at.

v  What is experience?

Experience  implies a second thing, i.e. duality. Unless one rise to a unity, he has no peace.

v  Why does man have wants, peace?

Because, he has sense of duality.

Without the  experience  there is no  duality . without duality thee is only non-duality. When one knows that all the three states is merged into the soul, the innermost self, and then there is noting to experience because there is no second thing other than Consciousness.  

Consciousness creates and in which the creator is dissolved. "Awareness is  the nature of the self”. The three states are dissolved in Consciousness. The waking or dream is a mirage; the waking or dream gets merged in Consciousness in sleep.

The whole waking or dream is merged in Consciousness in sleep, and then one gets the same position as soul or  Consciousness, the innermost self,  unconsciously in deep sleep.  But consciously becoming aware of the  soul or consciousness in the midst of the waking experience is non dual Self-Awareness.
