Mixing religion and spirituality is like mixing oil and water. Advaitic wisdom is pure Spirituality or Adyathma.+

There is a need to bifurcate religion from spirituality. People think religion is the stepping stone for Self-realization but it is not so. 

The 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 religious propagated beliefs are a myth.

Whereas Spirituality is based on the Spirit, which is the cause of the world in which we exist.

As one goes deeper in annals of 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 towards establishing Vedic religion overthrowing Buddhism. But even he was not able to avoid the influence of Buddhism. The influence of the revolutionary atmosphere of Buddhism has reappeared in the Advaita of Sage Sankara. His inability to revive 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 been 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 theistic (orthodoxy) Advaita is based on the dualistic perspective but Advaita philosophy is based on the nondualistic perspective. The theistic (orthodoxy) Advaita bifurcated from Advaitic philosophy. The theistic (dualistic) Advaita is meant for the ignorant populace.

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

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

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

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

Lots of 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. 

The rational proof is required so that one arrives at knowing the ultimate truth or Brahman i.e. Gnana. Theirs is mere dogma, parrotism, 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.

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 no different from Brahman.

This is the quintessence of Sage Sri, Sankara’s metaphysics. 

Remember:~

Religion is nothing to do with Advaita. Advaitic sect belongs to religion.  Advaitic wisdom is pure spirituality. Advaitic sect is dualistic is nothing to do with the Advaitic truth which is hidden by the illusion.

Mixing religion and spirituality is like mixing oil and water.

Religion is regarded as sacred and real by the common people, by the wise as false and by the rulers as useful.

The religion and its sects are based on the form, time, and space whereas the Spirituality is based on the Atman,  the formless, timeless and spaceless existence.

Religions hold birth, life, death, and the world as a reality. From the ultimate standpoint, the world in which we exist is an illusion created out he the Soul, which is present in the form of consciousness.

The seeker must know the difference between religion and spirituality. Many people think the religion itself as Spirituality.

Spirituality leads to discovering the truth which is hidden by form, time, and space.

Advaita is universal. Advaita is not for sale. Do not buy Advaita from the spiritual supermarket. Advaita is the nature of the Soul, the  Self. 

The world in which you exist is created out of single stuff. That single stuff is consciousness. Knowledge of the single stuff is Advaitic wisdom.

Advaitic truth is very simple, but it is very difficult to realize because you have accumulated mental garbage from different sources in the name of Advaita. 

Until you discard all the accumulated knowledge, you can never realize the Advaitic truth, which is beyond the form, time, and space.

The Advaita is the nature of the Soul, the Self shines in its own nondual awareness when wisdom dawns.

The Advaita is the Soul is the cause and the support of all that exists as the world in which we exist.

The Advaita is present in the form of consciousness. Advaita is the root element of the universe. 

From the Advaita, the universe comes into existence. In the Advaita, the universe resides. And into the Advaita, the universe is dissolved. The Advaita is the parent of all that is there is. : ~ Santthosh Kumaar
