Deeper inquiry, analysis reveals the fact that, when one limits the mind /’I’ to the physical entity, then it becomes ego/physical self. The mind is not limited to ego, but to the whole experience of duality [waking/dream].
The body, ego, world appear together and disappears together. Since our understudying and assimilation is based on the ego it becomes impossible cross the threshold of duality or mind. Therefore it is necessary to know the fact that ‘I’/ego is not the self, the self is that which pervades in everything and everywhere in all the three states, as their formless substance and witness. On the standpoint of the formless witness of the three states the three states are unreal. Thus the ego, body and the world are unreal, that is the waking also is as unreal as the dream.
