Advaitic wisdom of Sage Sankara is pure Spirituality is nothing to do with religion.+

Advaita is the universal truth. Advaita is the universal God. All dualistic Gods based on blind belief belong to dualistic illusion or Maya.  

Realize God right now and right here ~ means right in this very life, not in the next birth or next world.

You may be a Hindu, you may be a Christian, you may be a Buddhist, you may be a Muslim, or you may be a Jew but remember God in truth is not religious, because God is universal. 

Do not mix religion with spirituality. Religion is intended for those who are incapable of thinking rationally. 

The Advaitic wisdom of Sage Sankara is pure spirituality is nothing to do with religion. 

Sage  Sankara's  Advaitic wisdom is independent of religion. Religion is part of the dualistic illusion or Maya. God in truth or Brahman is the only reality and has nothing to do with religion.  

Remember, the ‘Self’ is not you but the Soul, which is present in the form of the Spirit or the consciousness.  The Soul, the innermost ‘Self’ is neither a Hindu, nor a Christian, nor a Buddhist, nor a Muslim because it is a formless timeless, and spaceless existence.

Remember the Soul; the Spirit is God in truth.  Religious Gods are mere beliefs. Belief is not God.  Religious God cannot be considered as a center because the Soul,  the ‘Self’ is the center of all that exists. 

Without the Soul, the world in which you exist ceases to exist, which means the religious God is dependent on the Soul for his existence. God in truth is only the Soul, which is present in the form of consciousness.

Even The Bhagavad Gita says: ~ “Brahmano hi pratisthaham ~ Brahman (God in truth) is considered the all-pervading consciousness, which is the basis of all the animate and inanimate entities and material. (14.27).

When Bhagavad Gita says God is considered the all-pervading consciousness which is the basis of all the animate and inanimate entities and material then nothing has to be accepted as God other than consciousness. 

Bhagavad Gita Chapter:~ All those whose intelligence has been stolen by material desires, they worship many Gods. (7- Verse -20)

Kena Upanishad (6) Chapter I: ~  “That which cannot be apprehended by the mind, but by which, they say, the mind is apprehended- That alone know as Brahman, and not that which people here worship.

Kena Upanishad (7) Chapter I:~  That which cannot be perceived by the eye, but by which the eye is perceived- That alone know as Brahman and not that which people here worship.

Kena Upanishad (8) Chapter I:~  That which cannot be heard by the ear, but by which the hearing is perceived- That alone know as Brahman and not that which people here worship.

Kena Upanishad (9)- Chapter I:~ That which cannot be smelt by the breath, but by which the breath smells an object- That alone know as Brahman, and not that which people here worship.

Even Brihadaranyaka Upanishad: ~ Brahman (God in truth) is in the form of the Athma, and it is indeed Athma itself.

Religious Gods are merely beliefs. Religious God cannot be considered as a center, because, the Soul and the innermost ‘Self’ is the center of all that exists. 

Without the Soul, the Self,  the world in which you exist ceases to exist, which means the religious God is dependent on the Soul for his existence.

Even Rig Veda: ~ The Atman is the cause; Atman is the support of all that exists in this universe. May ye never turn away from the Atman the Self. May ye never accept another God in place of the Atman nor worship other than the Atman." (10:48, 5)

The Brihadaranyaka Upanishad declares: "He who worships the deities as entities entirely separate from the Self does not know the truth. For the Gods, he is like a pasu (beast)". (1. 4. 10)

No mantras help to get rid of ignorance. All the mantras and rituals are meant for the ignorant populace, which strongly believes, in the illusory world in which they exist as a reality.  

For one who wants to acquire Self-knowledge or Brahma Gnana or Atma Gnana, the mantas will not help to realize the truth, which is beyond the form, time and space.

That is why Sage Sankara:~ VC~.61. For one who has been bitten by the serpent of Ignorance, the only remedy is the knowledge of Brahman. Of what avail are the Vedas and (other) Scriptures, Mantras (sacred formulae), and medicines to such a one?

VC-  v6~ 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.

Sage Sankara goes on to say: ~A sickness of not cured by saying the word “medicine.” You must take the medicine. Liberation does not come by merely saying the word “Brahman (God in truth).” Brahman must be realized. Until you allow this apparent universe to dissolve from your consciousness until you have realized Brahman, how can you find liberation just by saying the word Brahman? The result is merely noise. Until a man has destroyed his enemies and taken possession of the splendor and wealth of the kingdom, he cannot become a king by simply saying “I am a king.”

A buried treasure is not uncovered by merely uttering the words: “Come forth.” You must follow the right directions, dig, remove the stones and earth from above it, and then make it your own. In the same way, the pure truth of the Atman, which is buried under Maya and the effects of Maya can be reached by meditation, contemplation, and other spiritual disciplines but never by subtle arguments.

Sage Sankara’s Advaitic wisdom reveals: ~ Atman is the only one ultimate reality or Brahman or God in truth.

Advaita means the Soul, the Self, which is second to none. The Soul, which is present in the form of the Spirit or consciousness, is the ultimate truth or Brahman or God. Advaita is the nondual nature of God in truth. Advaita is the fullness of consciousness. : ~ Santthosh Kumaar
