Consciousness is the basis of all kinds of knowledge, presuppositions and proofs.+

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

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

The Soul, which is present in the form of consciousness, is real and eternal. The world in which we exist is an illusion created out of consciousness.

There is nothing exist prior to consciousness. The ‘I’ cease to exist without consciousness. The Soul, which is present in the form of consciousness, is the ultimate truth or Brahman.

That is why Bhagavad Gita: ~ “The permanent (consciousness) is always there, only the transient ‘I’ comes and goes. (2.18)

The ‘I’ hides the Soul, the God in truth.

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.

Brihadaranyaka Upanishad: ~ Brahman (God in truth) is in the form of the Athma, and it is indeed Athma itself.

The Soul is not limited to an individual. The individuals are many but the Soul is one. The individual exists within the universe. The Soul is the cause of the universe and it itself is uncaused. 

The Soul is not within the human body. The universe is created out of single stuff. That single stuff is the Soul, which is present in the form of consciousness. Thus, whatever universe contains is bound o be the Soul, which is present in the form of consciousness.

Like an ornament made from gold is Gold, which is born out of consciousness is consciousness. Like gold is a permanent thing, in ornaments made of gold, similarly, the mind, which is in the form of the universe is born out of consciousness, is consciousness in its essence.

Deeper self-search reveals the fact that you are not the Self, the world in which you exist is the Soul, which is present in the form of consciousness, but consciousness is specifically not an entity or identity or a thing within the world in which you exist. But it is the cause of the world in which you exist and it itself is uncaused.

The Soul is hidden within the world in which you exist. The nature of the Soul is the formless, timeless and spaceless existence.

Thus, it is necessary to realize the world in which you exist is created out single stuff, which is consciousness. Consciousness is the ultimate truth or Brahman or God in truth. Thus, God in truth alone is real; the world in which you exist is merely an illusion created out of consciousness. : ~ Santthosh Kumaar
