A Gnani sees duality as nonduality in the midst of duality because he has attained Gnana.+

Sage Goudpada: he was the first historic sage known to us to give a rational exposition of Advaita. He says that whatever is seen, whether external or internal, whether by the ordinary persons or yogis, is unreal.

Sage Goudpada: ~ To establish the truth of Non-duality by sheer reasoning alone. He begins by defining "What is real?" "What is unreal?" etc, because that is the right way to discuss or teach. People must first know what they are talking about. (Manduka Karika)

A permanent view of the world is an illusion that can come only after Soul centric reasoning; such knowledge cannot change. Were the seeker is sufficiently sharp he could grasp the unreal nature of the world by Soul-centric reasoning alone. To know the whole truth, one must know the whole universe, otherwise, he gets only half-truth.

Shruti has directly denied manifoldness in Brahman. The non-dual cause being an established fact, how could the phenomenal universe be different from It?

The Shruti has condemned (the belief in variety) in the words, “The person who”, being deceived by Maya, “sees variety in this (Brahman), goes from death to death”.

Since all beings are born of Brahman, the supreme Atman, they must be understood to be verily Brahman.

The Shruti has clearly declared that Brahman alone is the substratum of all varieties of names, forms, and actions.

The Shruti in the form of the Brihadaranyaka has declared that this Atman, which is the Self of all, is verily Brahman.

Renouncing the worldly life and accepting sanyasa or monk-hood means the incapacity to think deeper, impotency to inquire and reason.

Chandogya Upanishad -One who meditates upon and realizes the Self discovers that everything in the cosmos-- energy and space, fire and water, name and form, birth and death, mind and will, word and deed, mantram and meditation--all come from the Self.

Remember:~

Chandogya Upanishad: ~ “Whoever sees the Self in all does not see death, disease or diversity.

On the dualistic perspective, the individual experience of birth. Life, death, and the world are a reality.

From the non-dualistic perspective, the individual experience of birth. Life, death, and the world are an illusion.

Wherever there is duality there is the illusion. Wherever there is nonduality there is a reality.

A Gnani sees duality as nonduality in the midst of duality because he has attained Gnana.

First, the seeker has to know ‘what is the subject’ and ‘what is the object’. Deeper Self-search reveals the fact that”: the world in which we exist is an object to the formless subject. The formless subject is the Soul, which is present in the form of consciousness.

Deeper verification reveals the fact that the object and the subject are one in essence. That essence is consciousness. Thus, an object is only an illusion created out of the formless subject. Thus, in reality, the subject is real exists eternal.

The look of an object will depend upon the medium through which the observer views it. In fact, our mental and intellectual conditions determine the object (three states), observed, and experienced. The commoner viewing the object (three states) will see differently from a Gnani viewing the same three states. Each one interprets the three states that they see in terms of their existing knowledge. The commoner sees everything based on the ego, therefore, object (the world in which he exists as a reality), whereas a Gnani sees everything as the consciousness and he is fully aware of the fact that, there is no second thing that exists other than the Soul or the consciousness (subject). Thus, all objective observation has to be bifurcated to realize the ultimate truth, which is beyond form, time, and space. : ~ Santthosh Kumaar
