摩訶止觀 3.137

3.137

若經中有明五諦，六七八九乃至無量者，但得此意釋之，使入三諦也。十一智者，世智、他心智，兩種照俗諦；八智，觀真諦；如實智，觀中道。是名「智有離合而三諦不動」。

If in the sutras there is clarification of five truths, six, seven, eight, nine, up to an immeasurable number, one should merely take this principle to explain them, causing them to enter the three truths. As for the eleven wisdoms: mundane wisdom and knowledge of others' minds, these two illuminate the conventional truth; the eight knowledges contemplate the ultimate truth; the knowledge of reality as it is contemplates the middle way. This is called 'wisdoms having separation and combination while the three truths remain unmoved'.
