The unreal cannot have another unreality for its cause, nor can the real have the unreal for its cause. The real cannot be the cause of the real. And how utterly impossible it is for the real to be the cause of the unreal!
As a person within the waking experience through false knowledge appears to handle objects, whose nature is inscrutable, as if they were real, so also, in dreams, he perceives, through false knowledge, objects whose existence is possible in the dream alone.
Gnanis teach causality only for the sake of those who, afraid of non-creation, assert the reality of external objects because they perceive such objects and also because they cling to various social and religious duties.
Those who, because of their fear of the truth of absolute non- creation and also because of their perception of external objects, deny non-creation are not affected by the evil consequent on the belief in creation. This evil, if there is any, is insignificant.
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.
