Ultimate truth or Brahman cannot be known by intuition but it can be grasped from the reason based on the true self. Therefore, there is a need to know first the self is not physical but the formless consciousness. Then start reasoning on the base of the formless consciousness, all the clouds and confusion starts clearing on its own and finally one  will have no confusion left to say the illusion as a whole is spirit.

One knows everything within the waking experience is consciousness because the waking experience itself is a mere mirage created out of consciousness. The physical apparatus is absent in deep sleep, so one cannot know anything by intuition, because there is no duality in deep sleep. This proves that the duality is present only in waking or dream. And also   it proves that if there be such a faculty as intuition it must be limited to the physical self.

In Panchadashi:-  Atman The is the witness-consciousness that experiences the action, the actor, and the world of separate things. It is like a light that illuminates everything in a theatre, revealing the master of ceremonies, the guests, and the dancers with complete impartiality. Even when they all depart, the light shines to reveal their absence.

 People speak the supra-mental consciousness, who or what is there, to discover it because the mind is not there? It is an absurd statement.

The psychological writings of mystics and the pseudo-scientific explanations are not inferences from the facts of their mystic experiences but mere imaginations.

The mystic who says he has cosmic consciousness implies that he has astral travelled  and seen that this consciousness was also there in the astral world; even if we take his experiences as reality there is no truth in it because it is also mirage within the mirage. Until the duality persists as reality the non-dual reality will not be revealed. 

Those who object that the means and ends of waking are different from those of dreams, and therefore they are not on the same level, ignore that you have time, space and causal relation in both experiences. These three things make the waking experience real to everyone: and are its chief characteristics; similarly they give the same sense of reality to dream. They say waking is real and dream is illusory, but for the one who has learnt to view the three states  on the base of Ataman, which is in the form of consciousness as self, both are illusory.
