ABSTRACT
A deep and bottomless valley lies within the endless sky. Likewise, nihility lies within emptiness. But in this case, the sky is not only something that stretches far and wide over the valley, but also something within which the earth, we, and countless stars exist and are moving about. It lies under our feet, at a further depth of the bottom of the valley. If the residence of the omnipresent God is heaven, then heaven should also lie at a further depth of bottomless hell. So heaven is a depth for the hell. In the same way, emptiness is a depth for the nihility.1
