Just as a ripened fruit separates effortlessly from the tree and falls, when a truth seeker who is aiming to merge himself in the Atman attains maturity, he will definitely reach his non-dual destination and gets freedom from experiencing the duality as reality.
Every religionists/yogis /theorist are saying their own accepted truth, over and over again. They are merely propagating their truth, but none of them are able to establish it with certainty, which can be verified here and now, not in the next life or the next world.
Simply repeating /reading/hearing what the scriptures say or whatever god men or guru says does not make one to assimilate, understand and realize the non-dualistic or Advaitic truth. The seeker should not accept anything as truth, until he verifies the fact of all the claims, for himself by his own reasoning on the true base.
Seeker has to understand the fact that whatever is based on the form (universe) is falsehood and whatever is based on the formless [Ataman] is the truth. When the subconscious is able to discriminate everything on the base of Ataman, then it will start discriminating everything on the base of formless, and reject whatever is based on the form. Finally nothing exists to reject other then Ataman. Finally, the Ataman will prevail as ultimate truth.
Seeker has to establish the truth for himself by verifying himself by reasoning on the true base, not by blindly believing what others say, or what scriptures say. Once he creates a formless base mentally by replacing the form base which was discriminating good and bad, negative or positive in worldly life will start discriminating truth and untruth or real or unreal and start rejecting the untruth/unreal and starts accepting only truth /real.
Simply quoting the doctrines and sages will not help true seekers, in their pursuit of truth. Seeker has to use appropriate methodology for one to cognize those truths that are being stated within oneself by oneself. Truth pursuit is not an intellectual pursuit, but a spiritual understanding/realization.
Not by intellectual speculation but only by an awakening to the reality of his true existence he gets soulcentric vision. Soul, the innermost self’s nature is like state of deep sleep.
Religion, yoga and intellectualism are not the means to acquire self-knowledge or Brahma Gnana or Atma Gnana. Without getting rid of the ignorance and trying to get self-awareness through religion and yoga is like a sleeping man trying to know what he is about, without waking up. As sleep is to waking, so is ordinary life to the state of realization.
