Thus one remains in ignorance of his true existence,which is beyond form,time and space.

All these confusion will go on, until man thinks, he is an individual and apart from the world, and the world existed prior to him and he is born in it afterwards. Therefore, it is necessary to know the fact the true self is not ego, but the true self is the soul, and stop viewing and judging the world-view on the standpoint of the physical self (waking entity or ego), and one has to view and judge on the base of the soul, the innermost self to realize the fact that, the world along with man is illusion. The formless substance from which the illusion is created is Atman. Thus Atman is Brahman or ultimate reality. Thus no second thing exists on the standpoint of Atman or consciousness as self. thus there is no experience nor the experiencer in non-dual reality but only self-awareness.

By the knowing of the formless soul  as the  innermost  self, the three states becomes known.  Thus the formless knower of the three states is the soul, the innermost self. Till one becomes aware of the fact that,  the soul is the true self, he is bound to believe that the the waking entity is the knower and views and judges the worldview on the standpoint of the waking entity  as self.   Thus one remains in ignorance of his true existence,which is beyond form,time and space. 

Only through Self -knowledge or Brahma Gnana or Atma Gnana  the imperishable soul  is attained.  By means of the Self -knowledge or Brahma Gnana or Atma Gnana the one  beholds in everything and  everywhere  the soul,which is present in the form of consciousness. The consciousness 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, the innermost self.

Gnani who is in self-awareness, who lives as a householder/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 soul  alone. He assumes as the experiences of the three states (duality and non-duality). the 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 the  consciousnesses  fully in all things. 

Awareness is the nature of the soul, the innermost self.  The soul is present in the form of consciousness. The soul is in ignorance of its true nature in physical awareness. The physical awareness is present in the form of universe or waking experience. The soul is in its own awareness in deep sleep. We talk about the deep sleep experience in the state of ignorance (waking). The dream becomes unreal when waking takes place. Similarly the waking becomes unreal when wisdom dawns. Wisdom dawns when the waking entity realizes it itself is not the self in the midst of duality (waking).
