摩訶止觀 3.157

3.157

《成論》云：「前行後三中，後行前七中。七是業，復是道，能通後世；後三非業，而能通七，亦得是道。」經中亦呼為「十二牽連」、「十二輪」。束縛不窮，故名為「輪」；三世間隔，故名「分段」。覆真諦理，不得解脫，此即是病。說病即知藥，藥即從假入空止觀。觀藥即知病，故此惑為入空止觀所攝也。

The *Tattvasiddhi* says: "The former actions are among the latter three; the latter actions are among the former seven. The seven are karma and are also the path, capable of leading to future lives; the latter three are not karma, yet can lead to the seven, and thus can also be the path." In the sūtras they are also called the "twelve entanglements" and the "twelve-spoked wheel." Bound without end, they are called a "wheel"; separated across the three periods of time, they are called "fragmentary [birth and death]." Obscuring the principle of the ultimate truth so that one cannot attain liberation, this is the illness. When the illness is stated, the medicine is known: the medicine is the calming and contemplation of entering emptiness from the provisional. Contemplating the medicine, one knows the illness; hence this delusion is subsumed by the calming and contemplation of entering emptiness.
