大般涅槃經集解 67.42

67.42

案僧亮曰：一法一因，無量法無量因，說得其本，則一攝無量也。因善知識者，說信心則已攝盡也。菩提有二因，謂一從他聞法，即是善知識也；二謂內自思惟，即信心為本也。不離陰界入者，此三攝法斯盡也。

Sengliang comments: One dharma is one cause; immeasurable dharmas are immeasurable causes. If one speaks having grasped the root, then the one subsumes the immeasurable. As for 'relying on a good spiritual friend', speaking of faithful mind already subsumes it completely. Bodhi has two causes: first, hearing the Dharma from another, which is the good spiritual friend; second, inner reflection, which takes faithful mind as its root. As for 'not separated from the aggregates, realms, and entrances', these three subsume dharmas entirely.
