The ultimate truth is not connected at all with any argument because it is ever nondual.+

A Gnani is rational thinker, he discards all that is not rational. A rational thinker cannot look at the irrational words of the blind believer of religion.

A Gnani sees the words in a different way. The words have meaning only in ignorance whereas the truth is ever meaningless because it is free from ignorance.

The ultimate truth is not connected at all with any argument because it is ever nondual. 

Reality and illusion are one in essence. And that essence is the Soul, which is present in the form of consciousness. There is no second thing that exists other than the Soul, which real and eternal.

The whole universe is nothing but the Soul. Therefore, there is no second thing that exists other than the Soul, which is present in the form of consciousness.

It is not as if something that was not consciousness suddenly becomes consciousness. Rather, "knowing the truth” means a removal of the ignorance about one's own existence as consciousness. Thus, to "know the truth” is to "be consciousness."

Consciousness is ever-present. Without consciousness the universe, in which you exist cease 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.  

Remember:~

The world is the same in the cause of a Gnani and in the cause of the ignorant. A Gnani has realized the world in which he exists is an illusion created out of the Soul, which is present in the form of consciousness whereas an ignorant thinks the world, in which he exists is a reality.

The look of the world in which we exist depends upon the medium through which the Seer views it. In fact, our mental and intellectual condition will determine the world that confronts us observed, and experienced. A Gnani viewing the world in which he exists see differently for the ignorant viewing the same world. Each one of them interprets the world that confronts them in terms of their existing knowledge. A Gnani sees the world, in which he exists as the illusory play of the Soul, which is present in the form of consciousness whereas the ignorant see the world in which he is born, lives and dies as a reality.

A Gnani is the one who gained the Self- knowledge has realized the truth, which is hidden by the illusory form, time, and space. Gnani is fully aware of the fact that the Soul is the ‘Self’.

The Soul is the fullness of consciousness without the division of the form, time, and space. In the realm of the Soul the form, time, and space are one, in essence. That essence is consciousness. The Soul, which is present in the form of consciousness, is second to none. The Soul is the ultimate truth or Brahman or God in truth. : ~ Santthosh Kumaar
