Mentally reducing the universe into waking and waking into mind and mind into consciousness leads to self-awareness.

Seeker has to mentally rectify  the reasoning base from egocentric base  to soul-centric base  in order to get perfection in his understanding and assimilation of 'what is what' to realize ‘what is truth’ and ‘what is untruth’. 

Mentally reducing the universe into waking and waking into mind and mind into consciousness leads to self-awareness. 

The witness is not physical. Thus neither the waking entity nor the dream entity is not the witness the witness is that, which witnesses the three states without the physical apparatus. Thus viewing judging the the three states on the waking entity is erroneous. The three states (witnessed) are mere mirage on the standpoint of the formless witness, which is the soul (consciousness), the innermost self. 

The three states are product of ignorance. Only by getting rid of ignorance leads to Self awareness. Thus Self- Knowledge or Brahma Gnana or Atma Gnana is necessary in order to get rid of ignorance.

Ignorance is possible thorough soul-centric reasoning. 

      The first is by deeper inquiry and soulcentric reasoning.

      Second is from perfect understanding of what is what 

      The third is getting  firm conviction of what is truth  

Though inquiry, analysis and soul-centric reasoning leads to deeper understanding perfect grasping of ‘what is truth’ and ‘what is untruth’ leads to firm conviction and firm conviction leads to self-awareness. 

 The soul or consciousness is the formless substance and witness of the three states.  Deeper self search reveals the fact that,  the three states are created out of single stuff. That single  stuff is formless consciousness. Thus the three states are one in essence.  Thus there is no second thing exists other than the formless soul consciousness, the innermost self.  Realizing the soul or  consciousness as the innermost self is the goal of the truth seeker.  Soul, the innermost self is nothing to do with the three states, because the three states are mere mirage created out of consciousness. thus reaching the ultimate end and realizing the three states are nonexistent  leads to Self-awareness.
