From Yoga Vashista
That self is subtler even than space, since it has no name and cannot be described; neither the mind nor the senses can reach it or comprehend it. It is pure consciousness. The entire universe exists in the consciousness that is atomic, even as a tree exists within the seed but then the universe exists as consciousness and does not exist as the universe. That consciousness exists, however, because such is the experience of all, and since it alone is the self of all. Since it is, all else is.
