諸經要抄 1.36

1.36

涅槃經云　戒有二種。一者性自能持。二者須他教勅。若遇師僧白四羯磨。然後得戒。雖得戒已要憑和上諸師同學善友誨喻。乃知。進止聽法說法備諸威儀。是名須他教勅。

The Mahāparinirvāṇa-sūtra says: "There are two kinds of precepts: first, being able to uphold them by one's own nature; second, needing instruction from another. If one encounters an assembly of monks who perform the formal motion and three announcements (jñapti-caturtha-karman), only then does one receive the precepts. Although one has received the precepts, one must rely on upādhyāyas, masters, fellow students, and good friends (kalyāṇamitra) to instruct and guide one, so that one knows how to advance and stop, listen to the Dharma, preach the Dharma, and be fully equipped with all deportments. This is called needing instruction from another."
