大方廣佛華嚴經隨疏演義鈔 51.12

51.12

疏「一毫之善」下，即生公釋。《法華》一毫之善，發跡顯佛舉手低頭皆已成佛。言「無非佛流」，即《涅槃》意，乃至外道典籍亦佛法流，況內法耶？大小等教皆從如來大悲所流故。

In the commentary, 'a single tip-of-hair's worth of good' onward is Master Daosheng's interpretation. In the Lotus Sūtra, a single tip-of-hair's worth of good reveals the origin and displays buddhahood, so that raising a hand or bowing the head has already achieved buddhahood. Saying 'none is not an outflow of the Buddha' conveys the meaning of the Nirvāṇa [Sūtra], where even the scriptures of non-Buddhists are outflows of the Buddhadharma, how much more so internal teachings? This is because teachings of both the greater and lesser [vehicles] all flow forth from the Tathāgata's great compassion.
