Religious Gods are not real God. One must know God in truth.+

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. God in truth is only Atman, the  Self’. In reality, there is no duality, no differentiation. Only Atman exists. 

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

Religion can never make you know God because it propagates blind belief as God. Only an intense urge to know what God is supposed to be in truth can make you realize God.  

The Soul, the ‘Self is the Infinite God. 

The Soul is the Self. God in truth is the Soul, which is present in the form of consciousness. God in truth is the fullness of the consciousness without the illusory division of form, time, and space.  Therefore, there is nothing apart from it. 

God is Self-evident. God is not established by extraneous proofs. It is not possible to deny God because God is the very essence of the one who denies it. God is the basis of all kinds of knowledge, presuppositions, and proofs. God is within the universe in which you exist, God is without the universe in which you exist.

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

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.

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)

Vedas itself declares: May ye never accept another God in place of the Atman nor worship other than the Atman? Thus, to know the real God Self-realization is necessary. Self-realization is God-realization. Self-realization is itself real worship

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

People, who worship  Gods based on blind faith or blind belief hallucinate that they become one with such God.

How can you worship God? That implies two ~ the worshipper and the worshiped, 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 present 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.

God is the Supreme Being the One eternal homogeneous essence, indivisible consciousness, and intelligence, which is beyond form, time, and space. To which the Sages describe in a variety of ways through diverse words.

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

Only the path of wisdom leads the seeker of truth on his journey to the ultimate realization of the true nature of the Universal Essence, which is the Soul. The Soul is present in the form of consciousness.

Bhagavad Gita: 7: 19:~ "Such a man who has attained true knowledge, the knowledge of Self, the knowledge of Atman, worships ‘Self’ as~ Atman (God) alone exists~ everything is Atman, there exists nothing except Atman. Such a man is extremely rare."

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.

Brihadaranyaka Upanishad IV-13:~ ‘As a mass of salt has neither inside nor outside, but is entirely a mass of taste, thus indeed, has that Self neither inside nor outside but is altogether a mass of Knowledge. Just as a lump of salt has inside as well as outside one and the same saltish taste, not any other taste, so also that Brahman (consciousness) has inside as well as outside one and the same intelligence. Inside and outside are mental creations only. When the mind melts in silence, ideas of inside and outside vanish. The sages cognize one illimitable, homogeneous mass of consciousness only.

Causality taught in the Upanishads is only to enable us to understand the supreme truth of no-origination. The world is not different from the consciousness and the consciousness is not different from the Soul, the innermost Self, and the Soul is not different from the ultimate truth or Brahman. That the consciousness appears as the diverse world is only an illusion. If it really became diverse then the immortal would become mortal.

The dualists who seek to prove the origination of the unborn, by that very enterprise try to make the immortal, mortal. Ultimate nature can never change - the immortal can never become mortal and vice versa.

Sage Goudapada quotes from the Upanishads: ~ "There's no plurality here"; "The Soul through its powers appears to be many"; "those who are attached to the creation or production or origination 

Bible says: ~ “God is a Spirit, and they that worship God must worship God in Spirit and in truth. (John 4:24)  

The Spirit is the root element of the universe. The Spirit is present in the form of the Soul, the Self. The Soul is present in the form of consciousness. From the Spirit, the universe comes into existence. In the Spirit, the universe resides. And into the Spirit, the universe is dissolved. The Spirit is the parent of all that is there is.

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

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

Vedas says never accept another God in place of the Atman nor worship other than the Atman.

.
That is why Sage Sankara said:~ Talk as much philosophy as you like, worship as many gods as you please, observe ceremonies, and sing devotional hymns, but liberation will never come, even after a hundred aeons, without realizing the Oneness.

Hindus assert their religion is monotheistic, even though they honor a number of Gods, including Brahma the Creator, Vishnu the Preserver, and Shiva the Destroyer.  Hindus claim these various Gods are all manifestations of the oneness of the universe.  Hindu religious practices vary from place to place, but they frequently include yoga, physical and mental discipline to harmonize body and the Soul, and ritual bathing.

Belief in multiple Gods, The worship of idols; and worship of images that are not God, The worship of sacred images, ancestor worship, pilgrimage, priestcraft, the belief in avatars or incarnations of God, the hereditary caste system because all these lacks Vedic sanction.

Hinduism indulges non-Vedic beliefs such as idolatry, ancestor worship, pilgrimages, priestcraft, offerings made in temples, the caste system, untouchability, and child marriages. All these lack Vedic sanctions, therefore, Hinduism is not Ancient Vedic religion or Santana Dharma.

Realizing the universe is created out of single stuff and that single stuff is the Soul which is present in the form of consciousness leads to non-dualistic or Advaitic Self-awareness. Self-awareness is freedom or Moksha. Moksha is unity in diversity in the midst of duality.

It is very difficult to talk to people about the ultimate truth or Brahman because everyone thinks he knows the ultimate truth or Brahman or God in truth. 

This I know business is dangerous.  And whatever his reached conclusion is second-hand stuff.  Therefore, accepting accumulated knowledge without verification will lead the seekers to hallucinated realization based on the ego.  

One may have some flashes of truth when someone tries to indicate it through fewer words. But it takes nearer to the truth, not realization. :~Santthosh Kumaar
