The real cannot be described; it must be discovered and realized.+

The words betray the hollowness. The real cannot be described; it must be discovered and realized. Whatever the words try to convey is only helpful to grasp the truth. The nondual truth has to be grasped and realized. The man knows only the world and his individual experiences within the world. 

He is not aware of the fact that he and his experience of the world are part of the illusion. He views and judges the truth on the base of his birth entity, which is a false entity, thus he is stuck in the muck of illusion or duality. The nondual truth lies beyond the physical-based understanding. 

Thus, it is necessary to verify the fact through deeper inquiry, analysis, and reasoning about his own inherited beliefs and accumulated knowledge, in order to realize, how they become obstacles to realizing the truth. 

The physical conditioning of the soul will be dropped only when it realizes the fact that the waking entity or ego is not the Self.

Thus struggling to get rid of the ego, on the base of the ego is a foolish venture. Constant mental pounding is necessary through constant reflecting on the truth that, the soul is the true self and on the base of the soul all else is mere mirage/illusion. 

When one grasps these truths and becomes firm in his conviction the physical conviction drops and the nondual wisdom dawns. 

Thus, one becomes aware of the non-dual truth in the midst of the waking experience or duality or illusion.  

Remember:~ 

Advaitic wisdom or Self-Knowledge or Brahma Gnana or Atma Gnana is only being true knowledge, not the absence of duality. Self -Knowledge cannot destroy the world, but it eliminates ignorance and exposes the unreal nature of the mind or the universe.

Sage Sankara: - 63. Without causing the objective universe to vanish and without knowing the truth of the ‘Self’, how is one to achieve Liberation by the mere utterance of the word Brahman? — It would result merely in an effort of speech.

Sage Sankara: ~ “VC- 61. For one who has been bitten by the serpent of Ignorance, the only remedy is the knowledge of Brahman. Of what avail are the Vedas and (other) Scriptures, Mantras (sacred formulae), and medicines to such a one?

Yoga Vasistha:~ "Teachers, interpretations of sacred texts, the force of religious merit--none of these lead to the realization of that Ultimate Truth which is revealed in the clear reflection of the heart, engendered from contact with the good."

Anybody can write a commentary on the Upanishads and other great philosophic texts, all they need to do to pour out words. Some Westerners along with some orthodox pundits translated and published books, but all these books are based on the dualistic perspective.

All the knowledge of Advaita on dualistic perspective is merely egocentric imagination, not the truth, which is hidden by the ‘I’.

How does one get the knowledge?

What is meant by knowledge?

What is true knowledge?

–All this of which must be dealt with by the seeker of truth to realize the ultimate truth or Brahman.

The Self-knowledge or Brahma Gnana or Atma Gnana does not destroy the world, but it exposes the unreal nature of the world which appears as the waking. In the same way, the unreal nature of the dream was exposed when waking took place.:~Santthosh Kumaar
