First, know what this God supposed to be according to the Vedas.+

Until the seeker of truth drops all this priest-oriented baggage it is impossible to reach the ultimate end of understanding. Without reaching the ultimate end Self–Realization or God-realization is impossible.

No religious God can exist apart from the Soul, which is present in the form of consciousness.

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

The Vedas talk about Brahman (God in truth) which refers to the ultimate truth or ultimate reality. The consciousness is the ultimate truth, therefore, the consciousness is Brahman and Brahman is God.

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.

Vedas do not permit idol worship. All the idols are of the Puranic Gods priests are referring to the Puranic Brahma as God they are ignorant of the God in Vedas even though they speak of Vedas.

Priests do not understand the meaning of the Brahman, which is present in the form of consciousness. 

First, know what this God is supposed to be according to the Vedas. 

Rig Veda: ~ 'Prajnanam Brahma'- Consciousness is the ultimate reality or Brahman or God in truth.

God in truth is the Atman, the Self. Atman is present in the form of consciousness.

Do not accept any other God other than Atman not worship other than Atman.

Let these words be inscribed in your subconscious.

Nothing is real but God. Nothing Matters but love for God in truth. God in truth is everywhere and in everything.

God in truth is hidden by the illusory universe. God in truth alone is and all else is an illusion.

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)

Yajurveda: ~ There is no image of God in truth. God in truth is unborn and eternal. (Chapter 32, Verse 3)

Yajurveda: ~ God in truth is nondual and pure" (Chapter 40, Verse) 

Yajurveda – chapter- 32:~  God is Supreme Spirit has no ‘Pratima’ (idol) or material shape. God cannot be seen directly by anyone. God pervades all beings and all directions. 

Thus, Idolatry does not find any support from the Vedas.

From the Vedic perspective, all your religious Gods are non-Vedic Gods based on imagination.

Religious Gods are mere beliefs. Belief is not God.  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. God in truth is only the Soul, which is present in the form of consciousness.

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. 

How can you worship God? That implies two ~ the worshipper and the worshipped, whereas God is nondual. One can worship his idea of God only or realize his unity with it when he can’t worship it as apart.

When Upanishads and Vedas declare that, “God is in the form of the Athma, and God is indeed Athma itself” then why accept another God in place of the Atman nor worship other than the Atman.

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

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)

Swami Vivekananda: ~ The masses in India cry to sixty million Gods and still die like dogs. Where are these Gods?

 Knowing this, stand up and fight! Not one step back that is the idea. ... Fight it out, whatever comes. Let the stars move from the sphere! Let the whole world stand against us! Death means only a change of garment. What of it? Thus fight! You gain nothing by becoming cowards. ... Taking a step backward, you do not avoid any misfortune. You have cried to all the Gods in the world. Has misery ceased? The masses in India cry to sixty million Gods and still die like dogs. Where are these Gods? ... The Gods come to help you when you have succeeded. So what is the use? Die game. ... This bending the knee to superstitions, this selling yourself to your own mind does not befit you, my Soul. You are infinite, deathless, birthless. Because you are the 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. You are the entire world. Who can help you? - Swami Vivekananda  (Delivered In San Francisco, on May 28, 1900) -The Complete Works of Swami Vivekananda/Volume 1/Lectures And Discourses/The Gita II

That is why Sage Sankara,  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 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.”

Sage Sankara says:~   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.

The Atmic path is not for religious and yogic-minded people. Religious and yogic people must move on their chosen path. The Atmic path is for only seekers of truth who are seriously searching for the truth of their own existence.:~Santthosh Kumaar
