When man and his experience of world are part the illusion than what is the use of arguing as a man when the "Self" is not a man because "Self" is formless, birthless deathless eternal.

Self- knowledge or Brahma Gnana or Atma Gnana is the destroyer of ignorance.  Atman means the formless Soul. The Soul is present in the form of Consciousness. Consciousness is the innermost self. The nature of consciousness is formless and non-dual.

When one realizes his body, his ego his thoughts and  his experience of the world  are created out of single substance than by knowing the substance and realizing it as the innermost self,  is truth realization or Self-Realization.  

 It is foolish to argue on the base of waking entity and trying to prove the truth because the waking entity is false self within the false experience (waking) . On the ultimate standpoint all the three states are mere illusion.  Therefore it is necessary to learn to view the three states on the base of the soul, the innermost self.

When man and his experience of world are part the illusion than  what is the use of arguing as a man when  the "Self" is not a man because "Self"  is formless, birthless deathless eternal.    If one wants to unfold the mystery of his true existence he has to discard his physical shackle by realizing the self is not the form but the self is formless soul and base his self as formless  soul.  

On the standpoint of the formless soul or consciousness, the innermost self:- 

1.      The form, time and space are mere illusion.

2.      The universe is mere illusion.

3.      The mind is myth.

4.      The three states are mere mirage.

5.      The body, ego and the world are mere mirage

6.      The thinking, thought and thinker are part of the mirage.

7.      The doer doing and doing are part of the illusion.

Self- Knowledge is not brought about by any other means than soul-centric  reasoning .

one has to indulge in deeper self-search by inquiring:-   What is this ‘I’? How is this ‘I’ created? Who is its creator? Of what material is this ‘I’ made? This is the way of that inquiry and reasoning.
