Advaitic Gnana here is knowledge uncontradictable truth or scientific truth. This scientific truth of the whole, not a part is declared by Sage Sankara,+

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."

Eradicating ignorance completely is necessary. And this is possible only through ‘Self’-knowledge or Brahma Gnana or Atma Gnana.   Thus, there is no other road to freedom other than Gnana.  There is no other entrance other than Gnana.  The ignorance will vanish only when the nondual wisdom dawns.

Advaitic Gnana here is knowledge uncontradictable truth or scientific truth. This scientific truth of the whole, not a part is declared by Sage Sankara, and Sage  Goudpada  1200 years ago and thought only to those of higher intellect who are receptive.  

Thus karma and Upasana, yoga, and orthodoxy have to be bifurcated to realize the ultimate truth or Brahman.  

Mundaka Upanishad condemns rituals.  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)

Sage Sankara: ~ VC-  Let erudite scholars quote all the scripture, let Gods be invoked through sacrifices, let elaborate rituals be performed, let personal Gods be propitiated---yet, without the realization of one‘s identity with the Self, there shall be no liberation for the individual, not even in the lifetimes of a hundred Brahmas put together. (verses-6)

In spirituality the ultimate truth is God. The Atman is the ultimate truth or Brahman or God.

Sage Sankara’s wisdom has nothing to do with orthodox belief systems. Sage   Sankara is the only sage who has final authority on the Advaitic truth. The Advaitic truth is rational truth and scientific truth without dogma.

The Advaitic orthodoxy is not the means to acquire Self-knowledge or Brahma Gnana or Atma Gnana.  Advaitic orthodoxy is meant for the ignorant populace that is unfit to grasp the highest truth.   The Advaitic orthodoxy has nothing to do with the ultimate truth or Brahman.

All sect-based beliefs are dualistic and unphilosophical nothing to do with the ultimate truth or Brahman.  In spirituality the ultimate truth is God.  Thus, the Advaitic orthodoxy is a sect that has nothing to do with the Advaitic wisdom of the Sage  Sankara. Advaitic orthodox sect is meant for the ignorant populace.

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

The Advaitic truth is very simple. It is only to realize the world in which we exist is created out of single stuff.  Knowledge of a single stuff is Self-knowledge. Self-knowledge frees us all from ignorance.

We have to discard all accumulated knowledge accumulated from different Gurus and teachers.

Rest in the consciousness by realizing the world in which you exist is nothing but the consciousness. The Soul is the fullness of the consciousness without division of form, time, and space.  Thus the consciousness alone is real and eternal all else is merely an illusion created out of the consciousness.

Remember:~

A perfect understanding of ‘what is what’ is needed. Only an intense urge to know the truth, humility sincerity, and patience are the only qualifications to realize God in this very life and in this very world. 

Till you make sure intellectually the ‘Self’ is not within you but the ‘Self’ is hidden within the world, in which you exist and the world, in which you exist is nothing but an illusion created out of the consciousness, it is difficult to become Soulcentric. 

In the past, Self-knowledge or Brahma Gnana or Atma Gnana was imparted only to a few because sages of truth had preserved it people were more interested in their religious beliefs. Nowadays people are more advanced and capable of understanding assimilating, and realizing the truth beyond form, time, and space.

Start your journey even though you may find it difficult in the first as you go on reading the post your subconscious will start dropping the dualistic egocentric knowledge and start accepting the Soul-centric Self-knowledge or Brahma Gnana or Atma Gnana.

Everyone’s inner work is on. The Soul, the inner guru (Self)   guides us all till we get the stillness of its nondual true nature. 

As you raft upon which you cross the swift river to get to the other side; once you are on the other side of the shore; there is no longer any need to carry the raft. The far shore is the reality when you reach it, you can see quite clearly that there was never any river at all.

That is why Sage  Sankara says: ~ VC-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.

The Soul, the Self, which is present in the form of consciousness, is the only reality. In reality, there is no scope for two. Advaita means one without the second. Advaita means the Soul. The Soul, which is present in the form of consciousness, is one without the second.

The consciousness is one without the second because the world in which you exist is created out of consciousness. Thus, everything is consciousness. No second thing exists other than consciousness. The consciousness alone is real and eternal.

Advaitic truth has to be grasped mentally by realizing that form, time and space are one, in essence. : ~ Santthosh Kumaar
