Vision of wisdom means acquaintance with, and crystalline understanding of, the consciousness.

Vision of wisdom means acquaintance with, and crystalline understanding of, the consciousness. Mind, which is in the form of universe and the soul, which is in the form of consciousness are one in essence, consciousness is the formless substance and witness of the mind or universe.  So long as one has not realized the fact that the consciousness is the true self, he does not know what is real and what is unreal. With realization the seeker comes to know the distinction between real   and unreal, the essential and the contingent, the eternal and the evanescent, and this leads to his emancipation from the unreal.

The vision of wisdom eliminates duality; the manifest is clearly distinguished from the unmanifested. When the sense of duality is replaced by that of nondual consciousness, which is the true self.  

 Consciousness manifests itself as universe, which contains diverse things and forms. A Gnani knows that it is only the play of consciousness.
