 The previous characterizations of things as empty or as non-empty were both one-sided, as things are in reality neither empty nor non-empty. Rather, both Emptiness and all non-empty things are manifestations “the Center,” a tertium quid which is beyond but also includes both the ungenerated aspect and the generated aspect, at once both form and formless, the constant infinite productions of forms by the formless, formlessness present only as the infinity of forms. It is the collapsing of emptiness and non-emptiness into something that is immediately both: their unity, which is the real source of both: this is the Buddha-nature as “Exclusive Center” danzhong foxing 但中佛性, hidden beneath the two extremes, the inner kernel of all phenomena, as their source and ultimate reality.
