Disappointments may only come if one is not clear of the fact that, the self is not physical but the self is formless consciousness. The main idea is to realize the fact that, neither the waking entity nor the dream entity is the true self. The true self is the consciousness, which is the formless substance and witness of the waking or dream experience as a whole Thus to become awakened in to the true nature of the true self is important and everything is secondary.
Only after realization of the fact that, the self is neither the waking entity nor the dream entity but the self is the formless substance and witness of three states, one gets the ‘vision of unity in diversity.
The pure Consciousness assumes the forms of the three states. Consciousness though present in all the three states, it is not seen. Though it is light, it does not illumine. Though it always is, it is not in any place. It is indescribable. In its unity, where there is no duality, words become silent.
Nothing can be created, sustained and destroy when it does not exist in reality. Thus the creation and creator theory is reality within the illusion. The creation creator is mere theory based on ignorance. In the realm of truth there is neither creation nor creator. There is no second thing exists other than consciousness.
Consciousness has manifested duality in the form universe where there is not even a place for one! Consciousness becomes as vast as the sky, including the entire universe within itself. Within it even darkness and non-existence dwell.
The words, "soul” and "mind” refer to but one; the consciousness alone exists as universe or mind. Self-Knowledge is not an object of knowledge which requires various proofs to show that it exists; there is no doubt that it itself[soul or self] is the Guru. Its true nature is actionlessness is absolute, without any trace of activity.
