Religious God cannot be considered as the center because the Soul, the ‘Self’ is the center of all that exists.+

Religious propagated Gods are based on blind belief.  Religious God cannot be considered as the 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.

Even 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. 

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

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)

Brihadaranyaka Upanishad declares: "He who worships the deities as entities entirely separate from him 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, that the world in which he exists 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 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.” Brahman must be experienced. 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 perverted arguments. 

Lord Krishna says Ch ~V: ~ “Those who know the Self in truth." The last two words (tattvataha) are usually ignored by pundits, but they make all the difference between the ordinary concept of God and the truth about God.

The dualistic worship of "God” is only for the ignorant populace. The God in truth is only Atman, the  Self.   In reality,  there is no duality, no differentiation. Only Atman exists. :~Santthosh Kumaar
