摩訶止觀 3.131

3.131

次、明四諦離合者，前三諦、二諦、一諦皆豎辯；四諦則橫論。則有四種四諦，謂生滅、無生滅、無量、無作等。生滅四諦即是橫開三藏二諦也。無生四諦即是橫開通教二諦也。無量四諦即是橫開別教二諦也。無作四諦即是橫開圓教一實諦也。今將《中觀論》合此四番四諦。論云：「因緣所生法」者，即生滅四諦也；「我說即是空」，即無生四諦也；「亦為是假名」，即無量四諦也；「亦名中道義」，即無作四諦也。

Next, concerning the separation and combination of the four truths: the previous three truths, two truths, and one truth were all discussed vertically; the four truths are discussed horizontally. Thus there are four kinds of four truths, namely: arising and ceasing, non-arising and non-ceasing, immeasurable, and unconditioned. The four truths of arising and ceasing are the horizontal unfolding of the two truths of the Tripiṭaka. The four truths of non-arising are the horizontal unfolding of the two truths of the shared teaching. The four truths of the immeasurable are the horizontal unfolding of the two truths of the distinctive teaching. The four truths of the unconditioned are the horizontal unfolding of the one real truth of the perfect teaching. Now, applying the Mūlamadhyamakakārikā to match these four sets of four truths: the treatise states, 'Dharmas that arise from causes and conditions'—this is the four truths of arising and ceasing; 'I say are empty'—this is the four truths of non-arising; 'And are also provisional designations'—this is the four truths of the immeasurable; 'And also the meaning of the middle way'—this is the four truths of the unconditioned.
