The Vedas talk about Brahman (God) which refers to the ultimate truth or ultimate reality.+

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

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. 

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. 

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.

The Vedas confirm God is Atman (Spirit), the Self.

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)

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, “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.

They are steeped in ignorance and sunk into the greatest depth of misery who worships the matter, instead of the All-Pervading  Spirit (God), and those who worship things born of matter like trees, animals, man, etc. are sunk deeper in misery."

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

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)

Yajurveda says:~

Translation 1.

They enter darkness, those who worship natural things (for example air, water, sun, moon, animals, fire, stone, etc).

They sink deeper into darkness those who worship sambhuti. (Sambhuti means created things, for example, table, chair, idol, etc.) (Yajurveda 40:9)

Translation 2.

"Deep into the shade of blinding gloom fall asambhuti's worshippers. They sink to darkness deeper yet who on Sambhuti are intent."(Yajurveda Samhita by Ralph T. H. Giffith pg 538)

Translation 3.

"They are enveloped in darkness, in other words, are steeped in ignorance and sunk in the greatest depths of misery who worship the uncreated, eternal prakrti -- the material cause of the world -- in place of the All-pervading God, But those who worship visible things born of the prakrti, such as the earth, trees, bodies (human and the like) in place of God are enveloped in still greater darkness, in other words, they are extremely foolish, fall into an awful hell of pain and sorrow, and suffer terribly for a long time." (Yajur Veda 40:9.)

So, Yajur Veda indicates that:~

They sink deeper into darkness those who worship Sambhuti. (Sambhuti means created things, for example, table, chair, idol, etc.  (Yajur Veda 40:9)

Those who worship visible things born of the prakrti, such as the earth, trees, bodies (human and the like) in place of God are enveloped in still greater darkness, in other words, they are extremely foolish, fall into an awful hell of pain and sorrow, and suffer terribly for a long time." (Yajur Veda 40:9.)

When the religion of the Veda knows no idols then why so many Gods and Goddesses with different forms and names are being propagated as Vedic Gods. Why these conceptual Gods are introduced when the Vedic concept of God is free from form and attributes.

The Atman, God lies beyond the illusory experience of form, time, and space, because it is prior to any experience. 

Remember:~ 

The Soul, which is present in the form of consciousness, is the ultimate truth of Brahman or God.

All those whose intelligence has been stolen by ignorance believe God as an individual and separate from their own existence.

Sage  Sankara says: ~ “Brahman (Soul) is the truth The World is Unreal everything is Truly Brahman (Soul) and nothing else has any value.

Yajurveda – chapter- 32:~  God is Supreme Spirit.

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   ‘Self’. May ye never accept another God in place of the Atman nor worship other than the Atman?" (10:48, 5)

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

Thus, it refers to formless and attributeless God, which is the Atman (Soul), the innermost ‘Self’ within the false experience. Thus, it indicates clearly all the Gods with form and attributes are mere imagination based on the false ‘Self’. Thus Atman or Soul, the innermost ‘Self’ is God.

Vedas speak of one God that is the supreme ‘Self’ in i.e. Atman or Soul. Vedas indicates clearly all the Gods with form and attributes are mere imagination based on the false ‘Self’.

God in truth is neither personal nor impersonal because God in truth is not dualistic. God is in truth is ever free from the dualistic limitation of form, time, and space. God in truth is ever nondual. 

From nondual God's perspective, the form, time, and space are non-existent

If the form, time, and space are non-existent then the ‘I’ is non-existent

If the ‘I’ is non-existence then the mind is non-existent

If the mind is non-existent then the universe is non-existent

If the universe is non-existent then the waking is non-existence

If the waking is non-existent then God alone is real and eternal.

God is hidden by the ‘I’. The ‘I’ is the dualistic illusion. You are part and parcel of the dualistic illusion. The Soul is the cause of the dualistic illusion but the Soul itself is uncaused. 

The dualistic illusion is present in the form of form, time, and space. The form, time, and space are present in the form of the universe. The universe appears as waking or dream (duality) and disappears as deep sleep (nonduality).

Your existence is limited to the illusory form, time, and space. The form, time, and space are made of the same clay. That clay is the Soul, which is present in the form of consciousness. Knowledge of the single clay is Self –knowledge or Brahma Gnana or Atma Gnana. 

Self–knowledge or Brahma Gnana or Atma Gnana helps the seeker to unfold the truth (God in truth) hidden by the ‘I’, which is the dualistic illusion.

You have to draw your attention back every time it turns worldliness (I) and fixes it on the Soul or Brahman or God in truth. : ~ Santthosh Kumaar
