維摩經玄疏 3.82

3.82

First, as for the two truths outside the principle, there are two kinds: first, the non-identical two truths, which are the two truths of arising and ceasing; second, the mutually identical two truths, which are the two truths of non-arising. Thus the Dapin jing says: "Form is precisely emptiness; it is not that the cessation of form is emptiness." [Believing that] emptiness occurs only after form has ceased is the non-identical two truths; [realizing that] form is precisely emptiness is the mutually identical two truths.
