All belief-based religious Gods cease to exist without the dualistic illusion or Maya.+*****

Religious people think their inherited  belief in mythological God as reality but they are unaware of the fact that  their own existence within the universe  is a reality within the dualistic illusion or Maya.  

All the Gods, people believe and worship are a reality within the dualistic illusion or Maya and all belief-based religious Gods cease to exist without the dualistic illusion or Maya. The real God is hidden by dualistic illusion or Maya. God is hidden by Maya because the dualistic illusion or Maya is created out of God which is Atman, which is God in truth.

Vedas and Upanishad confirm the Atman, the Self, is present in the form of the Spirit or the consciousness is God in truth. 

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

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

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 innermost ‘Self’. In reality, there is no duality, no differentiation. Only Atman exists. 

Bhagavad Gita: ~ Brahmano hi pratisthaham ~ Brahman (God) 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 a God. 

Religious people believe the stories of the Jesus who raised the dead and Krishna who picked a mountain as a reality but Jesus who raised the dead and Krishna who picked a mountain within the dualistic illusion. Whatever belongs to dualistic illusion is bound to be an illusion.

Mythological God and Goddesses based on belief. The belief is not God. The belief implies duality. From the ultimate standpoint, the duality is merely an illusion. Thus, whatever one sees, knows, believes and experiences within the dualistic illusion is bound to be an illusion.

Mythological stories are a myth. Whatever is based on myth is merely a  superstition. Mythology was introduced in the past for the ignorant masses. It has to be discarded as one progresses in his spiritual advancement.

There is a clear cut idea of God in the Vedas, Upanishad and Bhagvad Gita. And also there is a clear cut idea of what not to worship as God in place of real God.  Thus, it proves on Vedic perspective the Puranic Gods are not Vedic Gods.

Remember:~

Swami Vivekananda: This bending the knee to superstitions, this selling yourself to your own mind does not befit you, the Soul. Self is infinite, deathless, and birthless. Because the Self is infinite Spirit, it does not befit you to be a slave. ... Arise! Awake! Stand up and fight! Die if you must. There is none to help you. Self is the entire world. Who can help you? - 

Mythology breeds superstition, blind belief, and senseless rituals and most irrational and gives them divine outlook.

Swami Vivekananda: ~ If superstition enters, the brain is gone. Superstition is our great enemy, but bigotry is worse.

Mythological contains stories of people with 10 with seven heads, etc., which are fables, yet are taken seriously by pundits.  All these stories are a reality within the dualistic illusion. The waking experience is the dualistic illusion or Maya.   Thus, whatever belongs to the dualistic illusion is bound to be a falsehood. In reality, there is no duality because there is only Oneness.  

That the ancient sages had miraculous occult power and books relate stories of their feats are fairy tales were meant for children, women and those whose minds had not developed.

When ‘Self’ is not ‘you’ than whatever you have seen, known believed and experienced as reality is bound to be an illusion. Thus, self-realization is necessary to realize your present the world in which you exist is merely an illusion.

 
If the present the world in which you exist is merely an illusion, then whatever you believed as a real with the world in which you exist is bound to be an illusion. The real God  is hidden by the illusion or Maya.:~Santthosh Kumaar
