Self-knowledge or Brahma Gnana or Atma Gnana is declared by the Indian sages in the past has to be mentally excavated from labyrinths of philosophy.

The Self –Knowledge or Brahma Gnana or Atma Gnana is goal of the true seeker.  Self-knowledge or Brahma Gnana or Atma Gnana is end of all egocentric knowledge.

Self-knowledge or Brahma Gnana or Atma Gnana is declared by the Indian sages in the past has to be mentally excavated from labyrinths of philosophy. So many conceptual divisions invented by teachers of philosophy by their excessive analysis and different idea of truth and interpretations. All these concepts and ideas are never ending process.

The seeker of truth need not take the path of doubt and confusion, which takes him nowhere.  Fortunate is the seeker who does not lose himself in the labyrinths of these theoretical philosophies.  By perfect understanding of ‘what is what’ leads to nondual self-awareness. Seeker has to behave in a   normal and sane way and silently reflect on the subject constantly.

Non-dualistic truth is supreme truth; all dualistic systems hold false self as real self and false experience as reality.  Non- dualistic wisdom is culmination of all systems including theistic nonduality.   The true non-dualist will not quarrel and argue with any theoretical philosophy because he is fully aware of the fact that, this orthodox theistic non-dualistic scholars or pundits like Dualist sages could not distinguish between ‘I’ and ‘formless witness.’ The 'I' was the witness. Their highest was the Jiva. One is so much attached to the 'I' that he do not want to think that 'I' does not exist. Again one is unable to detach the ‘I’ from the Real witness.  

There is need to study the scriptures. One has to self-search the truth and realize it without the scriptures. And then when he reads the scriptures he becomes aware the scriptures are also saying the same thing but everything is misinterpreted.  

 Mundaka Upanishad  :- This Atman cannot be attained through study of the Vedas, nor through intelligence, nor through much learning. He who chooses Atman—by him alone is Atman attained. It is Ataman that reveals to the seeker Its true nature. - 3 page70upanhsds by Nikilananda

It means the truth is beyond scriptures and egocentric intelligence.  Thus in order to grasp, assimilate and realize the non-dualistic truth the seeker to employ soulcentric reasoning faculty. 

That is why Sri, Sankara says in commentary in Vedanta sutra that what is accepted without proper enquiry will not lead a person to the final goal. On the contrary, such acceptance will result only in evil, in something which is detrimental to our spiritual progress.   Seeker of truth should not believe blindly in traditional orthodox nonduality without verifying all the facts from every angle. One has to reflect through reasoning over and over again without getting tired of the process.

That is why Sri, Sankara says  :- VC- 58. Loud speech consisting of a shower of words, the skill in expounding the Scriptures, and likewise erudition - these merely bring on a little personal enjoyment to the scholar, but are no good for Liberation.

59. The study of the Scriptures is useless so long as the highest Truth is unknown, and it is equally useless when the highest Truth has already been known.

60. The Scriptures consisting of many words are a dense forest which merely causes the mind to ramble. Hence men of wisdom should earnestly set about knowing the true nature of the Self.

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?

62. A disease does not leave off if one simply utter the name of the medicine, without taking it; (similarly) without direct realisation one cannot be liberated by the mere utterance of the word Brahman.

There is nothing more rational, more intelligible and more un-dogmatic insights of Sri, Sankara, is to drop all the theistic nonduality or Advaita which is meant for those who are incapable and not receptive to realize the ultimate truth or Brahman.

 If one merely theorises, tries to understand through his intellect and there contended he cannot become a Gnani but he becomes a scholar or pundit.   Seeker of truth must make what he has understood and assimilated has to be  realized, to get firm conviction of the non- dualistic truth or ultimate truth or Brahman,   than only it is possible for him to transcend all the limitations of the experience of form, time and space.    

The existence beyond limitations of form, time and space is known as Moksha or Nirvana. Spiritual freedom or self-realization is the goal of every seeker of truth.  –FORMLESS PATH
