The ultimate truth or Brahman has to be realized first then only it is possible to know what the scriptures are saying.+

Scriptures mastery, the force of religious merit--none of these lead to the realization of that Ultimate Truth or Brahman or God in truth.

Mundaka Upanishads: ~ So-called spiritual pundits and learned are called children because a child takes whatever it thinks as truth. The question never occurs to children “Is what I have seen or thought really the truth?" (P.334 line 9)

Scriptures are not needed in pursuit of truth. Even the Upanishads and the Advaitic Sages declare the same.

The ultimate truth has to be ascertained without the scriptures by realizing the Self is neither the waking entity nor the dream entity but the Self is Soul which is present in the form of consciousness. 

In the realm of truth the form, time, and space are created out of single stuff. That single stuff is consciousness. Realizing the single stuff as ultimate truth is Self-realization or truth realization. To realize this truth, there is no need for scriptures. 

The ultimate truth or Brahman has to be realized first then only it is possible to know what the scriptures are saying.

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.

Advaita is the nature of the Soul. Advaita is second to none. Advaita is universal wisdom that reveals on its own to all the serious and sincere seekers of truth.

The real Advaitic wisdom of Sage Sankara is soulcentric knowledge.  Self-knowledge or Brahma Gnana or Atma Gnana is soulcentric knowledge that destroys ignorance.:~Santthosh Kumaar
