The Upanishads clearly indicate:-
This Atman cannot be attained by the study of the Vedas, or by intelligence, or by much hearing of sacred books. It is attained by him alone whom It chooses. To such a one Atman reveals Its own form. (Katha Upanishad- Ch-II -23-P-20)
This Atman cannot be attained through study of the Vedas, nor through intelligence, nor through much learning. He who chooses Atman—by him alone is Atman attained. It is Atman that reveals to the seeker Its true nature. (3–page-70 Mundaka Upanishad -Upanishads by Nikilanada)
Gaudapada says that:- The merciful Veda teaches karma and Upaasana to people of lower and middling intellect, while Jnana is taught to those of higher intellect.
This clearly indicates that religion, which is based on individual conduct, prescribes karma and Upaasana to people of lower and middling intellect, therefore religion is for the lower intellect. And wisdom is for those are capable of inquiring into their own existence.
Brahman is considered the all-pervading consciousness which is the basis of all the animate and inanimate entities and material. (brahmano hi pratisthaham, Bhagavad Gita 14.27)
If Brahman is considered the all-pervading consciousness then, it is necessary to realize, the consciousness as self, which pervades all the three states to realize the fact that there is no second thing exists other the consciousness. Thus, consciousness [Atman] is ultimate truth or Brahman.
Even in the Buddhism: - Buddhist teaching has itself become a kind of interactive and self-evolving process, much like its idea of pratityasamutpada. However, the end goal is still Nirvana, which is an experience ultimately beyond all concepts and language, even beyond the Buddhist teachings. In the end even the attachment to the Dharma, the Buddhist teaching, must be dropped like all other attachments. The tradition compares the teaching to a raft upon which one crosses a swift river to get to the other side; once one is on the far shore; there is no longer any need to carry the raft. The far shore is Nirvana, and it is also said that when one arrives, one can see quite clearly that there was never any river at all.
They alone in this world are endowed with the highest wisdom who are firm in their conviction of the sameness and birthlessness of Ataman. The ordinary man does not understand their way. (Chapter IV — Alatasanti Prakarana 95-P-188 in Upanishads by Nikilanada)
Therefore, if one is seeking truth he has to know his true self is not physical but is the consciousness, which is in the form of consciousness.
Self-knowledge or Brahma Gnana or Atma Gnana cannot be attained by study of the Vedas and intellectual understanding or by bookish knowledge. Therefore there is no use of studying the Vedas and other scriptures in order to acquire the non-dual wisdom. That is why Buddha rejected the scriptures, and even Sri, Sankara indicated that, the ultimate truth lies beyond religion, concept of god and scriptures.
Thus it is necessary to follow the formless path dropping all the accumulated baggage and move forward to reach the destination in lesser time and effort.

Why You Are Not Your Brain, and Other Lessons from the Biology of Consciousness

Alva No, a University of California, Berkeley, philosopher and cognitive scientist, argues that after decades of concerted effort on the part of neuroscientists, psychologists and philosophers "only one proposition about how the brain makes us conscious ... has emerged unchallenged: we don't have a clue." The reason we have been unable to explain the neural basis of consciousness, he says, is that it does not take place in the brain. Consciousness is not something that happens inside us but something we achieve it is more like dancing than it is like the digestive process. To understand consciousness the fact that we think and feel and that a world shows up for us we need to look at a larger system of which the brain is only one element. Consciousness requires the joint operation of brain, body and world. "You are not your brain. The brain, rather, is part of what you are."
If the brain (body) is not the self then what is self? Therefore, there is a need to understand and assimilate the knowledge of the self through deeper inquiry, analysis and reasoning in order to unfold the mystery of the ‘I’.
There is no scope for debate and argument in pursuit of truth. Seeker has to verify the facts of any claim, if find them to be true then only accept them. It is not correct to impose idea on others when they are not ready to accept anything other than their accepted truth. There is no need to prove whether Buddha is right or Sri, Sankara is wrong. But seekers only mission is to know, how to realize the non-dual truth, which is propounded by the Buddha andSri,Sankara and Sri, Goudpada? Since present practices are based on conduct and action, and they are based on the false physical self (ego). What are the fatter and obstacle in realize the nondual truth? How to overcome the obstacle on the path of non-dual truth?
