Advaita is not a religious concept. Advaita is the nondual nature of existence hidden by the illusory dualistic universe.+

Sage Sankara cautioned that the study of the Upanishad alone would not lead to Moksha.

Ashtavakra:~There is no wisdom whatsoever in the scriptures-just a collection of words.

Discussion with the right people is always better than arguments with the wrong people. Silence is always better than meaningless.

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 Sanskrit literature, we find that the most frequently used term is “Advaita”.

Advaita is not a religious concept. Advaita is the nondual nature of existence hidden by the illusory dualistic universe.

Remember:~

Second Mundaka - Chapter 2 (7) - He who knows all and understands all, and to whom belongs all the glory in the world-, Atman, is placed in the space in the effulgent abode of Brahman. It assumes the forms of the universe. By the knowledge of that which shines as the blissful and immortal Atman, the wise behold Atman fully in all things.

Second Mundaka - Chapter 2 - The fetters of the heart are broken, all doubts are resolved, and all works cease to bear fruit when He is beheld who is both high and low.

Second Mundaka - Chapter 2 (9) - There the stainless and indivisible Brahman shines in the highest, golden sheath. It is pure; It is the Light of lights; It is That which they know who know the Self.

Second Mundaka - Chapter 2 (10) - The sun does not shine there, nor the moon and the stars, nor these lightnings, not to speak of this fire. When Brahman shines, everything shines after Brahman; by Brahman's light, everything is lighted.

Second Mundaka - Chapter 2 (11) - That immortal Brahman alone is before, that Brahman is behind, that Brahman is to the right and left. Brahman alone pervades everything above and below; this universe is that Supreme Brahman alone.

The misinterpretation is because of Buddha himself. Most of the questions were answered only by silence, leaving many to interpret as per their understanding. The enlightenment of Buddha and which again was indirectly accepted by Sage Goudapada. : :~Santthosh Kumaar
