摩訶止觀 3.167

四念處是慧性，觀攝。若作四意止說者，作心記錄不淨等，此屬止攝；而終是觀為主。四正勤，為成念處，一往觀攝。若兩惡不生，止攝；兩善為生，觀攝。四如意足，從四因緣得定，即果為名，止攝。五根：信、進、慧三根，觀攝；念、定，止攝。又，信、念兩屬。五力亦如是。七覺分：擇法、喜、進等，觀攝；除捨、定，止攝；念，通兩處。八正：正見、正思惟，觀攝；正業、正語、正命，屬戒，即止攝；正念、正定、正精進，止攝。四諦：三諦是有為行，屬觀門；滅諦是無為行，屬止門。十六行，皆是觀門。

The four smṛtyupasthānas are of the nature of wisdom, encompassed by contemplation. If explained as the four mental arrests—making the mind record impurity and so forth—this pertains to what is encompassed by calming; yet ultimately contemplation is primary. The four correct exertions, for the sake of accomplishing smṛtyupasthāna, in general are encompassed by contemplation: if two unwholesome states are not arisen, it is encompassed by calming; if two wholesome states are brought to arise, it is encompassed by contemplation. The four bases of psychic power attain concentration from four conditions and take their name from the result, being encompassed by calming. The five faculties: faith, vigor, and wisdom are encompassed by contemplation; mindfulness and concentration are encompassed by calming. Moreover, faith and mindfulness pertain to both. The five powers are likewise. The seven factors of awakening: investigation of phenomena, joy, and vigor are encompassed by contemplation; relaxation, equanimity, and concentration are encompassed by calming; mindfulness pertains to both. The eightfold path: right view and right intention are encompassed by contemplation; right action, right speech, and right livelihood pertain to morality and are encompassed by calming; right mindfulness, right concentration, and right effort are encompassed by calming. The four truths: three truths are conditioned practices, pertaining to the contemplation gate; the truth of cessation is unconditioned practice, pertaining to the calming gate. The sixteen aspects are all the contemplation gate.
