The awakened self needs no outside witness because it knows its own origin and end from within; it came from the light and returns to the light, and that inner certainty is its own proof. The knowing of whence and whither is the memory of the divine ground, the awareness that recognizes it is not the body but a current passing through it. Those who cannot tell are the faculties still bound to sense, which see only the surface man and have no sight of the source he rises from or the source he returns to. The self-witness is true because the one testifying is the very consciousness that watched itself descend into flesh and will watch itself ascend out of it.
The higher self is sure of itself because it remembers where it came from and where it is going, while the parts of a person that live by the senses see only the outer man and know neither.
