Soul/Atman is only which is permanent, unchanging in the ever changing three states is reality. Everyone hears of Soul or Atman or Consciousness but they can only imagine it.
One requires words only to distinguish between is there and not there, but he can't posit either of Reality, because his saying so is only an idea within the experience of duality, not reality. The reality is beyond words. Words are of use, however, as a thorn to pull out the thorn of other words that hinder knowledge.
Intellectually knowing the truth is only an imagination, whereas realizing the non-dual truth is knowing it as such.
People think that, by keeping out their thoughts will give experience of Atman or consciousness, which is the true self. How can one keep out a portion of consciousness his waking experience? It is utterly impossible. Such thoughtless experience is mere hallucination. It is impossible to experience any of the three states without consciousness, because the consciousness pervades in all the three states, as their formless substance and witness. Thus all the three states are mere mirage created out of consciousness, thus everything is consciousness. Therefore, no second thing exist other than consciousness in the experience of diversity. Knowing the diversity is created out of single stuff, which is consciousness, brings unity in diversity.
The thoughts arise only in waking/dream, and are non-extent in deep sleep. Thus the experience is prior to thought.
The yogi has got the idea of duality and therefore cannot realize truth. His experience of bliss is not Atamic Bliss is something one has to experience, therefore it will have to go as it came; hence it is only part of the illusion/duality. Yogis seek bliss through ignorance.
Intuition always implies knowing something, hence a second, hence it is rejected as duality. Even if it is intuition of the infinite, of bliss, God, etc., it is still a pointer to duality. Therefore the means to universal truth, i.e. Non-duality is not intuition, not mysticism but reason.
Yogis think meditation or actions which are other than Atman it is fundamental mistake. The very idea they concentrate on is itself Atman and hence needs no special effort. Yogi practice yoga as an individual within the false experience, thus he takes his body and the world as reality, thus yoga will not yield non dual truth.
It is impossible to treat one’s mind as different from Atman. The self- awareness i.e. consciousness must be there prior to the waking experience in which the yogi and the world exist: therefore it is a fallacy to believe that any yogic exercise can get self- awareness or self- knowledge.
The consciousness is within the three states as its formless substance and witness therefore it not correct to say consciousness is only within the physical body. One must know that consciousness is in everything and everywhere in all the three states. One has to realize the fact that, his body including all that he sees as universe is also is consciousness.
Ultimate truth is the summit of Non dual wisdom. It is the viewpoint of anything as reality, non-dual, whereas the religion deals with the relation between two things.
