Limiting the the soul to the individual entity is cause of ignorance. The soul is in the form of consciousness. the consciousness pervades in everything and everywhere in all the three states. The consciousness is our innermost self. The three states are mere mirage created out of soul. Soul is the whole experience of the three states. The ego /physical self is present within the waking or dream. The soul is within but always apart. There is no real difference between mind and the soul on the standpoint of the soul as self. The diversity is because of viewing and judging the worldview on the standpoint of the physical self. The mind is of identical essence with the soul. In the realm of truth the mind is one with the soul. It is as real and eternal.
The ego or physical self is not the true self. The veil of ignorance is the cause of experiencing the duality as reality. The illusion is superimposed on the Soul/self. Through self-knowledge one attains the non-duality and the duality ceases to exist as reality.
