As soon as word "mind" is uttered people think “the mind of an individual", whereas the mind appears and disappears as a whole waking or dream. The body and the world is within the mind. Thus individual and individual experiences are happenings within the mind.
Witness means which is aware of the appearance and disappearance of the three states.” This is an important and vital difference. The mind appears to the witness, which is the formless soul. The soul is in the form of consciousness. The soul is also the substance of the mind.
Mirage or illusion means which appears to be reality but by close examination one becomes aware of the unreal nature of the mind. The mind appears in the form of the universe. Universe appears as waking or dream. until one becomes aware of the formless substance of the mind it is difficult to understand and assimilate self-knowledge.
There is always confusion and there is no clarity about truth, if one considers the waking entity as self. Therefore, the self cannot be the waking entity but the self is the formless consciousness[soul]. on the base of the consciousness as self there is no confusion and always clarity.
When the mind appears all confusion and doubts arise. And when mind disappears all will the doubts and confusion will vanish. Then what is that is aware of the appearance disappearance of the mind. The physical existence [man + universe] is limited to mind, and it is mind. Therefore, mind is limited to the physical existence.
One cannot make the mind clear; without understanding the formless substance from which the mind is made. The nature of the mind is diversity. Thus understanding the mind is necessary to understand and assimilate the ultimate truth.
Mind is mere illusion. If one never verifies the facts about the mind than he will remain ignorant about the facts about what is mind. Without verifying the fact about the mind, one keeps experiencing the duality as reality. When the illusion is taken as reality all the judgments will be based on the waking entity, which is false self, within the false experience. Thus all conclusions based on the waking entity will be based on the intellectual speculations; therefore one will not be able to grasp, understand and assimilate the ultimate truth.
Only when one investigates the mind through deeper self-search than he will be able to transcend the mind. The clarity comes only when he knows the mind is not within the body but man and universe are within the mind. There is no such a thing as a mind in the realm of truth; never has been and never will be. Mind means the illusion, in which the whole universe with all its contents exists. When there is no mind than there is no illusion.
