The orthodoxy Advaita bifurcated from Advaitic path of wisdom. The orthodox Advaita is dualistic and is meant for the ignorant populace.+

Sage Sankara was an independent thinker. His wisdom has not been taken seriously by many in India because most of the followers of Sage Sankara are religious orthodox.

It is that philosophy in India was for centuries more an exposition of the ancient classics than the independent thought of individual thinkers as in ancient Greece or modern Europe and America.

Sage Sankara and Sage Goudapada are independent thinkers other schools of Indian philosophy are mere theologies.

The Advaitic wisdom of Sage Sankara is the only tool to unfold the mystery of the ‘I'. The dualistic philosophy cannot escape the charge of dogmatism.

Remember:~

As one goes deeper into annals of the history he becomes aware of the fact that the so-called present Hinduism has adopted many things from Buddhism, the religion of Abraham, Jainism, and Islam. If one goes deeper enough he will become aware everything is mixed up and messed up in time.

Sage Sankara endeavored toward establishing the Vedic religion and overthrowing Buddhism. But even he was not able to avoid the influence of Buddhism. The influence of the revolutionary atmosphere of Buddhism reappeared in the Advaita of Sage Sankara. His inability to revive the Vedic religion that flourished before the Buddhist revolution in its pure form is discernible.

No one is taken pains to rectify it because; because people have inherited them, from their ancestors and they think it is blasphemy even to hear anything against their inherited religion and belief. Once one gets involved with the religious class it is the end of the pursuit of truth.

The orthodoxy Advaita is based on a dualistic perspective but the Advaitic wisdom of Sage Sankara is based on the nondualistic perspective. 

The  orthodoxy Advaita bifurcated from Advaitic path of wisdom. The orthodox Advaita is dualistic and  is meant for the ignorant populace.

Moksha or freedom is the same thing in spirituality. Different religions have different ideas of Moksha. Religious moksha is nothing to do with sprituality or Adyathma.

In India Advaita and Dvaita is a merely religious traditions, which they inherited from their ancestors. No one questions their validity because it is considered blasphemy to question their religion, their Gurus, and Godmen or the pundits.

People who are attached to their religious code of conduct and trying to preach Advaita, which is mixing the individual life, and the concept of God.

All mixed-up hotchpotch teachings are not the Advaitic wisdom of Sage Sankara.

Religious Gurus themselves are not aware of the fact that individuality and their worldly life are part of the illusion.

Sage Sankara said:~ Talk as much philosophy as you like, worship as many Gods as you please, observe ceremonies, and sing devotional hymns, but liberation will never come, even after a hundred aeons, without realizing the Oneness.

According to Advaita Vedanta, the Veda addresses itself to two kinds of audiences - the ordinary ones who desire the transitory heaven and other pleasures obtained as a result of ritual sacrifices, and the more advanced seeker who seeks to know Brahman. Thus, the Purva mimam. sa, with its emphasis on the karma kanda of the Vedas, is meant for the first audience, to help lead its followers along the way. However, the Vedanta, with its emphasis on the jnana kanda, is meant for those who wish to go beyond the dualistic illusion (ignorance).

Remember:~

Sage Sankara and Sage Goudpada are independent thinkers other schools of Indian philosophy are mere theologies. Advaitic philosophy is real philosophy. The dualistic philosophy cannot escape the charge of dogmatism.

Advaitic wisdom propagated by Sage Sankara is from a non-dualistic perspective.

There is a need to bifurcate religion from spirituality. People think religion is the stepping stone for Self-realization but it is not so. Religion is based on ignorance and it keeps the seeker permanently in ignorance by hiding the truth with its mythical beliefs and dogmas and superstition. According to Vedas and Upanishads, all the religious propagated beliefs are a myth.

 Spirituality is based on the spirit, which is the cause of the universe in which we exist.

There is no need to study neither Advaita Vedanta nor Vedas nor Buddhism to realize the ultimate truth or Brahman. It is no use going roundabout way; trace the Brahman.

Philosophy does not begin with the ultimate truth. The ultimate truth has to be proved, not assumed. Hence, so-called philosophers who take Brahman for granted are not philosophers at all.

Orthodox Advaitin scholars will teach that all is yourself, but none of them can show that this is so, none has analyzed it scientifically, and none can prove it. Rational proof is required so that one arrives at knowing the ultimate truth or Brahman i.e. Gnana.

Orthodox Advaitin scholars' knowledge is based on dogma, parrotism, and repetition of what they read in scripture. Authoritarianism merely assumes as true what another says, but what has yet to be proved.

Sage Sankara said:~ Talk as much philosophy as you like, worship as many Gods as you please, observe ceremonies, and sing devotional hymns, but the liberation will never come, even after a hundred aeons, without realizing the Oneness.

Remember:~

Sage Sankara gave out what was of most use to the greatest number of people. Therefore, in the commentaries on the Upanishads, such as the famous Manduka Upanishad, he gave the highest non-dual message of the identity of Atman and Brahman, revitalizing the philosophy and practice of Advaita, while in the commentaries on the Brahma Sutra he gave lesser teaching, posting both higher and lower Maya and higher and lower Brahman (Ishvara) to explain creation for those of lesser intellects until they were ready for the highest truth.

Only through Self-knowledge or Brahma Gnana or Atma Gnana's negation of duality is possible. The Soul, which is present in the form of consciousness, is the ultimate truth or Brahman or God in truth.

Consciousness is the cause of the origin, maintenance, and withdrawal of the universe is Advaita (i.e. non-dual), which means that consciousness transcends all conceptions, positive and negative. Nothing positive can ever be imagined or said about it.

Consciousness is existence absolute, awareness absolute. The existence absolute means that consciousness is not unreal or non-existent. And it is not unconsciousness. Nothing positive can be stated about consciousness.

The nature of the Soul, the ‘Self’ is the non-dualistic awareness. Non-dualistic awareness is like a deep sleep state. The non-dualistic awareness indicates that the nature of the Soul, the ‘Self’ is inexplicable, indescribable, and unimaginable.

Sage Sankara ’says:~ Gnana is common to all religions.

There is nothing like One Gnana for a Hindu and another for a Christian.

The entire philosophy of Sage Sankara can be summed up in the following statement:-

Brahma Satyam, jaganmithya, jivobrahmaivanaparah: - Brahman alone is real; the world is non-real, and the individual ‘Self’ is essentially not different from Brahman.

This is the quintessence of Sage Sankara’s Advaitic wisdom. : ~ Santthosh Kumaar
