When the mind is dropped consciously through wisdom, then the self (consciousness) arises in its true nature, and then there is only the oneness. One becomes fully aware of the fact that, the diversity [mind or universe] is mere mirage created out of consciousness. One has to grasp the fact that, the mind, which is in the form of universe, is identical with the formless source from where it arises. Thus there is no duality in the true nature of the true self, which is consciousness. The duality is reality only on the base of false self, which is the ego. The ego is the false entity within the false experience [three states].
The true self [consciousness] is within the three states and it is without the three states and also it is apart from the three states. It is apart because it is the formless knower of the three states, which comes and goes. The three states depend on the formless knower [witness] for their existence but the formless knower can exist with or without the three states. This has to be grasped mentally in order to reach the witness consciousness.
