Only through Self- Knowledge or Brahma Gnana or Atma Gnana the Self-Awareness is attained.

By the knowing of  formless soul  or consciousness as the  the innermost self,  the three states becomes known.  Thus the formless knower of the three states is the soul or consciousness. only when  one becomes aware of the fact that,  the formless  soul is the true self, he is bound to believe that the body is the knower and views and judges the worldview on the standpoint of body [ego] as self, thus remain ignorant of the fact that,  the formless  soul consciousness is the innermost self.

Only through Self- Knowledge or Brahma Gnana or Atma Gnana  the Self-Awareness  is attained.  By means of the Self-Knowledge one  beholds in everything and  everywhere consciousness, which otherwise cannot be seen or seized, which has no root or attributes, no eyes or ears, no hands or feet; which is eternal and omnipresent, all—pervading and extremely subtle; which is imperishable and the source of  three states.

Ignorant, dwelling in ignorance, but wise in their own conceit and puffed up with vain scholarship, wander about, being afflicted by many ills, like blind led by the blind.

People, immersed in ignorance in various ways, flatter themselves, saying: We have accomplished life's mission. Because these performers of karma do not know the non dual Truth owing to their attachment, they will never be able to cross the ocean of duality or cycle of birth, life and death.

People regarding religious rituals, god glorification and sacrifices and humanitarian works as the highest, do not know any higher good. By expecting reward for their good deeds they remain in the clutches of duality and fully ignorant about the soul,or consciousness, the innermost self. 

Gnani who is in non-dual  self-awareness, who lives as a householder or commoner  and never poses himself as man of knowledge, but helps and guides the serious seeker as a fellow seeker by inspiring them  until they reach their non dual destination. 

Gnani knows all and understands all and fully aware of the fact that, the experiences of the three states belongs to the formless  soul alone. He assumes as the experiences of the three states [duality and non-duality]. formless soul or consciousness dwells in the three states as its formless clay. By the knowledge of that formless clay which shines as the blissful and immortal soul, the Gnani behold soul or consciousness the true self fully in all things.
