摩訶止觀 3.164

3.164

○四、止觀攝一切行者，前智是解，解而無行，終無所至。行有兩種，所謂慧行、行行。若三藏中慧行、行行，乃至圓中慧行、行行。慧行是正行，行行是助行。

5.4 Calming and Contemplation Encompassing All Practices: The preceding wisdom is understanding; if there is understanding without practice, one will ultimately arrive nowhere. Practice is of two kinds: so-called wisdom-practice and conduct-practice. From the wisdom-practice and conduct-practice in the Tripiṭaka up to the wisdom-practice and conduct-practice in the perfect [teaching]: wisdom-practice is primary practice, and conduct-practice is auxiliary practice.
