God in truth is the Atman, the Self. Atman is present in the form of consciousness.+

Dualists have introduced the concept of God with attributes when Yajur Veda says: ~ 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. Therefore, all these add-ons prove that the form and attribute-based concepts are introduced by some sages of the past with a new belief system and code of conduct in the name of Vedas.

It clearly indicates that: -If the human goal is to acquire Self-knowledge or Brahma Gnana or Atma Gnana then why indulge in rituals and glorify the conceptual Gods and Goddesses to go into deeper darkness. Instead, spend that time moving forward towards Self-knowledge, which is one’s prime goal.

Since it is eternal and infinite, it comprises the only truth. The goal of Vedic religion, through the various yogas, is to realize that consciousness (Atman) is actually nothing but Brahman.

The Vedic pantheon of Gods is said, in the Vedas and Upanishads, to be the only higher manifestations of Brahman. For this reason,- "ekam sat" (all is one), and all is Brahman.

Rig Veda: ~ 'Prajnanam Brahma'- Consciousness is the ultimate reality or Brahman or God in truth.

God in truth is the Atman, the Self. Atman is present in the form of consciousness.

Do not accept any other God other than Atman not worship other than Atman.

Let these words be inscribed in your subconscious.

Nothing is real but God. Nothing Matters but love for God in truth. God in truth is everywhere and in everything.

God in truth is hidden by the illusory universe. God in truth alone is and all else is an illusion.

Kena Upanishad (1) Chapter II:~ If you think: "I know Brahman well," then surely you know but little of Its form; you know only Its form as conditioned by man or by the Gods. Therefore Brahman, even now, is worthy of your inquiry.

Kena Upanishad (2) Chapter II:~ The disciple said: I think I know Brahman. The disciple said: I do not think I know It well, nor do I think I do not know It. He among us who knows the meaning of "Neither do I not know nor do I know-knows Brahman.

Kena Upanishad (3) Chapter II:~ He by whom Brahman is not known, knows It; he by whom It is known, knows It not. It is not known by those who know It; It is known by those who do not know It.

Kena Upanishad (4) Chapter II:~ Brahman is known when It is realized in every state of mind; for by such Knowledge one attains Immortality. By Atman one obtains strength; by Knowledge, Immortality

Kena Upanishad (5) Chapter II:~ If a man knows Atman here, he then attains the true goal of life. If he does not know It here, great destruction awaits him. Having realized the Self in every being, the wise relinquish the world and become immortal

Thus, the goal is to realize the Atman (consciousness). The Atman (consciousness) is nothing but Brahman. 

Realizing Atman (consciousness) as Brahman (ultimate truth) is truth realization or Self-realization. 

There is no need to follow religion, study the scriptures, or glorify the Gods and the Gurus and follow the path of doubts and confusion by losing oneself in the labyrinths of philosophy to get Self-realization when there is an easier path. 

By mentally tracing the source of the mind, from where it rises and subsides, one becomes aware of the fallacy of the mind, which rises as the duality (universe or waking or dream) and subsides as the nonduality (deep sleep). The mind rises from consciousness and subsides as consciousness.:~ Santthosh Kumaar
