It really depends on his inborn natural capacity of the seeker to understand and assimilate Sage Sankara’s Advaitic wisdom.+

Religious Scholars or pundits believed it is enough to read, to accumulate knowledge from books. They think they have mastered Vedas and Upanishads and the other scriptures, and they looked upon other people as ignorant, as illiterate people who are not studied Vedas and Upanishads.  

In one sense, you can say   Gnani is illiterate because his Gnana is nothing to do with scriptural mastery. If you consider a scholar as literate, as a well-educated man, then a Gnani is definitely illiterate.

But of what value is the scholar’s accumulated knowledge? A scholar will go on and on about the immortality of the Soul but when death approaches you will find him trembling and weeping and wailing. All this talk of immortality will crumble into nothingness because he has not known it.

The garbage of religious beliefs dogmas superstitions is confounded with the human imagination. The great reality of the glory of the religious Gods is hyped and obscured by so much tinsel and commercialism.

Spirituality is not theology.  Advaita is not a philosophy, but Advaita is the ultimate truth or Brahman or God. Advaita is Self-knowledge or Brahma Gnana or Atma Gnana or knowledge of the Spirit or God in truth.

The word “Advaita” is one without the second.  Advaita essentially refers to the Atman and the whole existence. Advaita is the fullness of consciousness without the division of form, time, and space.

Remember:~

Theology is nothing to do with spirituality. Advaita is pure spirituality. The theological Advaita is nothing to do with the Advaitic wisdom, which is based on the Spirit the Atman. 

Theological Advaita is conceptual having its own doctrine is nothing to do with the Gnanic Advaita because Gnanic Advaita is Self-knowledge or Brahma Gnana or Atma Gnana.

Both approaches are not workable together because the theological Advaita is based on the birth entity (ego)   Gnanic Advaita is based on the Atman (Soul). Thus, the theological Advaita has to be discarded without mercy to get Advaitic Gnana.   

“Advaita” is a term used variously to express the unity of reality.  Advaita is unity in diversity.  

The seeker has to begin by defining "What is real?" "What is unreal?   to establish in Advaitic reality by sheer reasoning alone.   The reasoning is the right way to realize the truth, which is beyond form, time, and space. People must first know what is the truth. and what is untruth’.  

Sage Sankara’s wisdom is not teaching but universal wisdom. Advaitic wisdom is neither a teaching nor a theory, but it is mere guidance to those who are seriously seeking the ultimate truth or Brahman. Grasp the ultimate truth anytime, at any age, if the seeker has the spiritual maturity and capacity to grasp it. 

Sage Sankara says: ~ VC-47   All the effects of ignorance, root, and branch, are burnt down by the fire of knowledge, which arises from discrimination between these two—the Self and the not-Self.

It really depends on the inborn natural capacity of the seeker to understand and assimilate Sage Sankara’s Advaitic wisdom.   Sage Sankara’s wisdom is a Self-examiner, to test oneself to discover how near to Gnana he has approached and what progress has already been made on the path, and what still remains to be done.  It sets up a criterion for Self-judgement.   There are millions in search of truth, but one in million will be able to grasp it.

Without Sage Sankara, there is no Advaita (nonduality).  Since it was mixed up with orthodoxy there is a lot of confusion. I am highlighting all the obstacles, which is blocking one from realizing the ultimate truth or Brahman. There are so many non-dualistic masters of the east and also from the west who expound Advaitic or non-dualistic knowledge, but none of them are helpful to reach the ultimate end.

One has to know and realize his innermost Self is the Soul and identify it as his true identity to find liberation from the bondage of the illusion of birth, life, death, and the world(duality).   The goal of our life is to find and realize our identity with our Soul, which is the real Self. 

Sage Sankara said:~ Neither by the practice of yoga nor philosophy, nor by good works nor by learning, does liberation come, but only through the realization that Atman and Brahman are one in no other way.(1) Vivekachoodamani v 56, pg. 25

To come to a more precise understanding of what non-duality is or might mean, we must return to the original linguistic and philosophic backgrounds from which the word has been translated into English.

 If we limit a probe of the meaning of non-duality to Hindu Sanskrit literature, we find that the most frequently used term is “Advaita.

Advaita” is not a religious concept.  Advaita is the nature of the existence hidden by form, time, and space.   The seeker has to attempt to rule out from the start a false understanding of reality by a perfect understanding of ‘what is what’.

The Advaita is hidden by the dvaita. Advaita is the Soul, which is present in the form of consciousness. Dvaita is the universe.

Advaita is basically a denial; it is literally the negation of the dvaita.  That means whatever remains by negating the universe by realizing the universe is created out of single clay and that clay is the Soul, which is present in the form of consciousness.  Consciousness is the cause of the universe and it, itself is uncaused. 

Remember:~

Sage Sankara strongly advocated the study of Upanishads, and at the same time cautioned that the study of Upanishads alone would not lead to moksha. In matters of such as spiritual attainment, one’s own realization was the sole authority and it cannot be disputed

Sage Sankara also said the study of Upanishad was neither indispensable nor a necessary prerequisite for attaining the human goal, the moksha.

Sage Sankara pointed out; that even those who were outside the Upanishad fold were as eligible to moksha as those within the fold were. He declared that all beings are Brahman, and therefore the question of discrimination did not arise. All that one was required to do was to get rid of ignorance (Avidya or duality).

Remember:~

That is why Sage Sankara says: ~ VC 56. Neither by Yoga, nor by Sankhya, nor by good work, nor by learning, but by the realization of one's identity with Brahman is Liberation possible, and by no other means.

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 that 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 utters the name of the medicine, without taking it; (similarly) without direct realization one cannot be liberated by the mere utterance of the word Brahman.

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.

64. Without killing one’s enemies, and possessing oneself of the splendor of the entire surrounding region, one cannot claim to be an emperor by merely saying, ‘I am an emperor’.

65. As a treasure hidden underground requires (for its extraction) competent instruction, excavation, the removal of stones and other such things lying above it, and (finally) grasping, but never comes out by being (merely) called out by name, so the transparent Truth of the Self, which is hidden by Maya and its effects, is to be attained through the instructions of a knower of Brahman, followed by reflection, meditation and so forth, but not through perverted arguments.

66. Therefore, the wise should, as in the case of disease and the like, personally strive by all the means in their power to be free from the bondage of repeated births and deaths.

Then there is no need for the scriptures, religion, and idea of God. One has to be more rational to realize the Advaitic truth, which is the ultimate truth or scientific truth.:~Santthosh Kumaar
