Some Saints recommended repeating the God’s name as a spiritual practice but what is the use of such practice without knowing ‘what God is in actuality.+

Yajur Veda – chapter- 32:~ ‘God Supreme or Supreme Spirit has no ‘Pratima’ (idol) or material shape.  God cannot be seen directly by anyone. He pervades all beings and all directions. Thus,   Idolatry does not find any support from the Vedas.

Some Saints recommended repeating God’s name as a spiritual practice but what is the use of such practice without knowing ‘what God is in actuality.  Such practices are based on religious God.  The God in truth is without the form, without the time and without space, and without the name. Religious Gods are not God in truth.

If you repeat the name of nameless God you will remain in the prison of ignorance. Thus, it is necessary to realize ‘what God is supposed to be in actuality. All prostrated prescription keeps one in the prison of ignorance.

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 Vedas confirm God is Atma, 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).

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

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 (God), which is present in the form of consciousness. 

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 the real exists.

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)

That is why Sage Sankara: ~ VC 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 (verses-6)

The mantra-yoga consisting of repeating the name of God, or even the AUM; thousands of times yield nothing. It can appeal only to the ignorant, to those who cannot think deeper. It is merely a religious fable. The real exercise is to think of the meaning of the name or the AUM and then only do you get something.

That is why Sage Sankara: ~ ‘VC- 63- Without causing the objective universe to vanish and without knowing the truth of the ‘Self’ how is one to achieve Liberation by the mere utterance of the word Brahman? — It would result merely in an effort of speech.

The religion preaches that Gods have forms and attributes and the ways to God are many. It simply tries to lead them to darkness with its dogma and idea of many Gods, which is apart from the Self. 

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

 Humanity has to awaken to the reality of its true existence by realizing the world in which humanity exists is merely an illusion created out of the consciousness through Self-knowledge or Brahma Gnana or Atma Gnana.

Self-knowledge or Brahma Gnana or Atma Gnana frees the Soul, the Self from the cage of the dualistic illusion. : ~ Santthosh Kumaar
