The truth seekers main Goal is Self-realization. The Self-realization is truth realization. Truth realization is God realization.+

The truth-seekers main Goal is Self-realization.  Self-realization is truth realization. Truth realization is God-realization.

The seeker must realize the truth of his true existence. Thus, Self-realization is very much necessary to unfold the mystery of the ‘I’.

As one goes deeper self-search he becomes aware of the fact that the ‘Self’ is not the ‘I’ but the ‘Self’ is I-less’ ~ Soul or Atman. The Soul is present in the form of consciousness. 

Even The Bhagavad Gita says: ~ 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. 

The Soul is the Self. The Soul is present in the form of consciousness.  The Soul is the cause of the universe and it itself is uncaused.  The Soul is the ultimate truth or Brahman. Brahman is God.

The universe hides the God in waking (duality) and God hides the universe in deep sleep (nonduality).

God in truth is the Soul or Atman.

Advaita means the Soul, the Self, which is the best. The Soul, which is present in the form of the Spirit or consciousness, is the ultimate truth or  Brahman or God in truth. Advaita is the nature of God, the  Self. Advaita is God. Advaita is the fullness of consciousness.

Vedas and Upanishads confirm Atma is God. 

In Yajurveda – chapter- 32:~   It has been said that God Supreme or 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 innermost 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 in the form of the Athma, and it is indeed Athma itself.

The Upanishads say in effect that ~ If you believe that the Soul is one and God (Brahman) is another you cannot understand Truth.

Brihad Upanishad: ~ “If you think there is another entity, whether man or God there is no truth."

Ish Upanishads: ~

MANTRA 10

Vidya and Avidya both are hindrances to Self-knowledge, but Vidya is even worse than Avidya. The word Vidya is used here in a special sense; here it means worshipping Gods and Goddesses. By worshipping Gods and Goddesses you will go after death to the world of Gods and Goddesses. But will that help you? The time you spent there is wasted because if you were not there you could have spent that time moving forward towards Self-knowledge, which is your goal. In the world of Gods and Goddesses, you cannot do that, and thus, you go deeper and deeper into darkness.

Avidya is Karma and, therefore, a hindrance. You perform Avidya - i.e., you perform Agnihotra and other sacrifices. This is a roundabout way of purifying the mind, and it is also groping in the dark. But it may not have as heavy a toll on your time and energy as the other.

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

When Upanishads itself says they are steeped in ignorance and sunk into the greatest depth of misery who worships the matter, instead of the All-Pervading God(Atman)  and those who worship things born of matter (illusion)  are sunk deeper in misery then why worship God in place of the real God., which is Atman.

The dualistic worship of personal “Gods” 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.

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 innermost 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 worshiper and the worshiped, whereas the 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.

Why worship and glorify the Gurus and Yogis (human form)   in place of God when Veda bars such activities and it also warns people who indulge in such activities 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

Vedas bars human worship: ~

Translation:~ 

"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.)

Sage Sankara says: 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. 

The seeker of truth has to accept the truth as God and reject the untruth to realize other Atman the real God and all else is an illusion created out of the Atman the only God.:~Santthosh Kumaar
