Understanding what is God is a not so easy. Religious people can only imagine God based on their beliefs.***

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)

The 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)

The Sages of truth are not religious Gurus or Saints.  The religion and its mythological Gods and mythological Gods are nothing to with the ultimate truth or Brahman or GOD.

All sect based beliefs are dualistic and unphilosophical nothing to do with the ultimate truth or Brahman.  In spirituality, the ultimate truth is God.

Lord Krishna confesses that the oldest wisdom of India (Advaitic wisdom ) has been lost: people misinterpret and falsify it today as they did then. It is not yoga but the philosophic truth. But nobody knows it. The teachers of philosophy and leaders of mysticism or religion do not want to inquire into truth and have no time for it. (Gita ~ Chap ~IV~ v.2)

In Gita Chap.IV where Lord Krishna says: ~ “This yoga has been lost for ages" the word yoga refers to Gnana yoga, not other yogas: the force of the word this is to point this out.

Lord Krishna describes some of the other yogas but devotes this chapter separately to Gnana yoga. So one sees even in those ancient days people did not care for Advaita; they wanted religion; hence Gnana got lost. That is why Krishna calls it "the supreme secret." Krishna points out that the yoga must see "Brahman in action."

Gita Chap.IV:~ “He who achieves perfection in Yoga finds the Self in time." This means that after his yoga is finished, he begins the inquiry into ultimate truth and in due course this inquiry produces the realization of the universal spirit as the result.

Understanding what is God is a not so easy. Religious people can   only imagine God based on their beliefs.

That is why Lord Krishna Says Ch ~V: ~ “Those who know me 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.

No dualities, no differentiation. Only Atman exists.

The 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)

It proves that the all-pervading Atman, which is present in the form of the  consciousness, is God.   Thus worshipping the form based Gods is meant for the ignorant populace who are incapable of the realizing the truth, which is beyond the form, time, and space.  

Lord Krishna Says Ch ~V: ~ “Those who know me in truth.".

~ Know me in truth means know the ‘Self’ without the form, time, and space.

There are two kinds of audiences - the ordinary ones who desire the transitory heaven and other pleasures obtained as a result of ritual sacrifices, and the more advanced seeker who seeks to know the truth beyond the form, time and space. The Bhagavad Gita is meant for the first audience, to help lead its followers along the way. The Advaitic wisdom is meant for those who wish to go beyond  the form, time, and space. 

All sect based beliefs are dualistic and unphilosophical nothing to do with the ultimate truth or Brahman.***

The Indian Sages of truth, who believed in the realization of the immortal Soul as the Self, frees the Soul from the illusory prison of experience of the birth, life, death and the world.   When the soul wakes up from its sleep of ignorance and consciously remains in its own awareness in the midst of the dualistic illusion is Moksha.

There is no other goal other than Self-realization is the supreme goal within the dualistic illusion.

The Soul is appeared as the world in which we exist, the world in which we exist is nothing but an illusion created out of the Soul, which is present in the form of the consciousness.

 The Soul is the God. The Soul alone is the ultimate truth or Brahman.  The Soul, which is present in the form of the consciousness, is without the second.

 The truth is ever truth and the untruth is the untruth, the untruth hides the truth.

The Soul is what gives the sentient to the illusory world in which we exist.  The Soul pervades everywhere and in everything in the world in which we exist.  The Soul is the fullness of the consciousness unlimited by the form, time, and space.  it is self-luminous, existence and awareness.  None can deny it because it is the basis of the very world in which we exist. Denying the existence of the Soul is denying the world in which the denier exists.  

The world exists because of the Soul.  The Soul is the innermost Self.  The Self is not you but the Soul, which is the cause of the world in which you exist.  The Soul is not within your body because the Soul, which is present in the form of the consciousness pervades everywhere and in everything in the world in which you exist.

Drop the idea is that the Soul is within your body.  Mentally detach the Soul from the world in which you exist by realizing the world in which you exist is mere an illusion created out of the Soul, which is present in the form of the consciousness. therefore, the world in which you exist is mere an illusion created out of the consciousness. if the world in which you exist is mere an illusion then there is no second thing exist other than the consciousness. Thus, everything is the consciousness.

Sage Sri, 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 influence of Sage Sri, Sankara’s wisdom is nothing to do orthodox belief systems.

All sect based beliefs are dualistic and unphilosophical nothing to do with the ultimate truth or Brahman.  In spirituality, the ultimate truth is God.

Some philosophers in the past dissented from this interpretation of Vedanta philosophy, holding that the incarnated Souls were separate from the Divine Essence and only finally merged with it after the cycles of birth.  All these theoretical philosophy is based on the imagination based on the false self (ego or you) within the false experience (waking).

The scientific knowledge is limited to form, time and space. The Self-knowledge  or Brahma Gnana or Atma Gnana is beyond the form, time, and space.  The birth, life, death and the world are within the domain of the form, time, and space. The Soul, the innermost Self, is formless, timeless and spaceless existence.

The consciousness is ever present. Without the consciousness the world, in which you exist cease to exist.   The consciousness is Self-evident. It is not established by extraneous proofs. It is not possible to deny the consciousness because it is the very essence of the one who denies it. The consciousness is the basis of all kinds of knowledge, presuppositions, and proofs. The consciousness is everything. Thus, the consciousness is the ultimate truth or Brahman.
