摩訶止觀 3.18

3.18

絕待止觀則不可說，若有四悉檀因緣故亦可得說。若有世界因緣則會異而說；若有為人因緣則通三德而說；若有對治因緣則相待而說；若有第一義因緣則絕待而說，說為止觀。此之名字，不在內、外、兩中間，亦不常自有。是字不住、亦不不住。是字不在橫四句、竪四句中，故言是字不住；亦不在無橫無竪中，故言亦不不住。是字不可得故，故名「絕待止觀」，亦名「不思議止觀」，亦名「無生止觀」，亦名「一大事止觀」。

Calming and contemplation of absolute transcendence cannot be spoken of, yet if there are the conditions of the four siddhāntas, it can also be spoken of: if there are mundane conditions, it is spoken of by reconciling differences; if there are conditions for the benefit of persons, it is spoken of by connecting to the three virtues; if there are therapeutic conditions, it is spoken of relative [to defilements]; if there are supreme truth conditions, it is spoken of through absolute transcendence—spoken of as calming and contemplation. These words are neither inside, nor outside, nor in between the two, nor do they eternally exist of themselves. These words neither abide nor do they not abide. These words are not within the horizontal four propositions or the vertical four propositions, hence it is said that these words do not abide; nor are they in the absence of horizontal and vertical, hence it is said that they also do not not abide. Because these words are unobtainable, it is called "calming and contemplation of absolute transcendence", also called "inconceivable calming and contemplation", also called "calming and contemplation of non-arising", and also called "calming and contemplation of the one great matter".
