Advaitic Orthodoxy accepts God in many forms and names. Sages Sankara declares the Atman is Brahman. That is the Soul, which is present in the form of consciousness is the ultimate truth or Brahman. That is the ultimate truth is God. And the ultimate truth itself is worthy of Godhood.

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 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

Brihadaranyaka Upanishad: ~ The Self is indeed Brahman (God), but through ignorance, people identify it with intellect, mind, senses, passions, and the elements of earth, water, air, space, and fire. This is why the Self is said to consist of this and that and appears to be everything.

Yajurveda says: - if one worships what is not God: ~

Translation 1.

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

They sink deeper in 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 into darkness deeper yet who on sambhuti is 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 in darkness those who worship sambhuti. (Sambhuti means created things, for example, table, chair, idol, etc ~(Yajurved 40:9)

Those who worship visible things born of the prakrti, such as the earth, trees, and 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.)

The Hindus believed in polytheism, believing all of their Gods to be separate individuals, which was introduced much later by the founders of Hinduism which contains diverse beliefs caste, and creed.

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.:~Santthosh Kumaar
