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

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

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

From a nondualistic perspective, the individual experience of the 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 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 exists other than the Soul or consciousness (subject). 

Thus, all the objective observation has to be bifurcated to realize the ultimate truth, which is beyond form, time and space.: ~ Santthosh Kumaar
