The scholar’s knowledge is limited to the form, time, and space whereas Gnani's knowledge is of the beyond the form, time, and space.+

Dattatreya's Song of the Avadhut 1.36-42:~ “Non-duality is taught by some; some others teach duality. They don't understand that the all-pervading Reality is beyond both duality and non-duality.

Mundaka Upanishad:~   “ The Para or Higher knowledge is the knowledge of the Supreme Being while the Apara or Lower Knowledge is that of following sacrificial rites and ceremonies. (1/2/ 1 – 6)

A Gnani may be illiterate in the dualistic world, a scholar as literate, or a well-educated person in the dualistic world.  The scholar’s knowledge is limited to the form, time, and space whereas  Gnani’s even if he is illiterate his knowledge is beyond the form, time, and space.

Sage Sankara: ~ On Gnani: "The knower of Brahman wears no signs. Gives up the insignia of a monk's life…his signs are not manifest, nor his behavior." 

When the knower of Brahman wears no signs ~ it means he does not identify himself as a Guru or a teacher or a yogi. 

A scholar will go on and on about the immortality of the Soul but when death approaches he will be trembling and weeping and wailing. Scholars, interpretations of sacred texts, the force of religious merit--none of these lead to the realization of that Ultimate Truth or Brahman.   Self-knowledge or Brahma Gnana or Atma Gnana is the knowledge of the immortal Soul, the one and only ‘Self’ of all that exists as an illusion. 

All this talk of immortality will crumble into nothingness because he has not known the knowledge of the Soul, which is immortal.    

A Gnani knows what he is talking about is not an explanation, what he is talking about is the realization of the truth, which is beyond the form, time, and space.

A Gnani shares his joy by sharing his wisdom; he is singing the song about the unsung truth.  Remember whenever a Gnani speaks about God it is not a belief; he knows it, it is his realization. He is talking out of his realization; hence, he can be of immense help to the whole of humanity.

A Gnani always sees the world in which he exists as the Soul without any division of form, time, and space.  And a Gnani watches his own actions as if they were another's.  he is never puffed up by the praise or disturbed by blame.  

As for Gnani, his individuality is dead. It is merged in the Soul like waves in the ocean   A Gnani living in freedom has gone beyond the dualities of life.  

A Gnani is not competing with anyone, he is alike in success and failure and content with whatever comes to him.  He is e free, without Selfish attachments; his attention is fixed in the awareness of the Soul.  

A Gnani performs all practical duties of the practical world like others and he helps other seekers to get rid of the ignorance of their true existence. 

Remember:~ 

Sage Sankara strongly advocated the study of Upanishads, and at the same time cautioned that the study of Upanishad alone would not lead to moksha. In matters 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; 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).

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
