The mind (universe) merges into Consciousness and remains not as mind, but as the formless soul ( Consciousness) without duality in the midst of duality.

The mind (universe)   merges into Consciousness and remains not as mind, but as the formless  soul ( Consciousness) without duality in the midst of duality. When the consciousness becomes aware of its own  true nature then there is no duality it is non-dual existence, which is ultimate reality. 

In ignorance or illusion, one first forgets the soul (Consciousness), which is the true self, and views and judges the worldview on the false self(waking entity or ego).  All the memories belong to the false self, not to the true self, which is formless. The false self is dependent on true self for its existence.  Therefore, on the standpoint of the true self (soul) the memory is mere illusion because it is based on the false self within the false experience.  

 It is the Self that is in illusion and it is the self that gets free from the bondage of the illusion. The illusion is present in the form of mind. Mind is in the form of universe. Universe appears as waking or dream and disappears as deep sleep.  The individual experiences of birth, life, death and the world are within the waking experience.  The dream is parallel waking experience and waking is parallel dream.

Deeper self-search reveals the fact that the, self is neither the waking entity nor the self is the dream entity but the self is formless soul, which witnesses the coming and going of the three states in succession without the physical apparatus.  This has to be mentally grasped and assimilated to realize the formless soul, the innermost   self is nothing to do with the three states. On the standpoint of the three states, the three states are mere illusion.

The practical life within the practical world, which is present as waking experience, is mere illusion. If waking experience is mere illusion than the individual experience of birth, life, death and world are mere illusion.   If the experience birth, life death and the world are mere illusion, it means the form; time and space are mere illusion.  If form, time and space are mere illusion, it means the past, present and future is mere illusion. Thus it is necessary for the seeker to realize the fact that,   form, time and space are one in essence, in order to realize the three states are one in essence. That essence is consciousness. Thus all the diversity is created out of   formless consciousness. Thus no second thing exist other than consciousness, the innermost self. Seeker of truth has to constantly reflect on the subject in order to get firm conviction of the truth.  Seeker has to reflect on the same truth again and again until it becomes reality. One needs to constant reflect on the subject until he gets firm conviction of what is what.
