In between

Since all phenomena (or phenomenally appearing things) which arise, present no reality in themselves, they are said to be of noumena (in other words, they are of the Voidness, regarded as the noumenal background or Source of the physical universe of the phenomena). Though not formed into anything, yet they give shape to everything. Thus it is that phenomena and noumena are in unison, and said to be of one nature. They are, like ice and water, reflection and mirror, two aspects of a single thing.
