Advaitic truth is supreme truth; all dualistic systems hold false self as real Self and false experience as a reality. Advaitic wisdom is the culmination of all systems including the theistic Advaita.
There is no need to discuss argue and quarrel with those who think they know the truth. There is no need of any support of scriptures to acquire Self-knowledge or Brahma Gnana or Atma Gnana. Theistic Advaitic orthodoxy is nothing to do with the Advaitic wisdom. The theistic Advaitic orthodox scholars or pundits like Dualist sages could not distinguish between ‘I’ and ‘formless witness of the ‘I’.
They take the ‘I’ as the witness. They are stuck to the reality of the ‘I’, all their theories are based on the ‘I’. All the ‘I’ based theories are the false theories
They are so much attached to the 'I' that they do not want to think that 'I' does not exist. Again they are unable to detach the ‘I’ from the Soul, the Real witness.
There is no need to study the scriptures. The seeker has to self-search the truth and realize it without the scriptures. When he realizes the truth, which is beyond the form, time and space then he reads the scriptures he realizes some of the scriptures are also saying the same thing, but everything is misinterpreted.
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."
When the ultimate truth is rightly known and one attains eternal life thereby. Through Soul, the innermost Self he gains strength and through its knowledge immortality.
Advaitic truth cannot be realized by intellectualism but only by perfect understanding of ‘what is the truth?’ and ‘what is the untruth?’.
The soulcentric vision when you learn to view and judge the world which confronts you on nondualistic perspective.
The nature of the Soul, the innermost self’s is like state of deep sleep.
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 Nikilanada
It means the truth is beyond scriptures and egocentric intelligence. Thus in order to grasp, assimilate and realize the Advaitic truth the seeker to employ soulcentric reasoning.
That is why Sage Sri, Sankara says in the 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, then 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.
The Self –Knowledge or Brahma Gnana or Atma Gnana is goal of the true seeker. Self-knowledge is end of all egocentric knowledge.
