大方廣佛華嚴經隨疏演義鈔 36.14

36.14

疏「禪定持心常一緣」等者，即第三十三經。彼具明十度云「如其迴向行布施，亦復堅持於禁戒，精進長時無退怯，忍辱柔和心不動」，禪定下同，今此但取明定慧文耳。

Regarding the commentary's citation, "Dhyāna concentration holds the mind always on one object", and so forth: this is the thirty-third fascicle of the sūtra. It fully explains the ten pāramitās, saying: "Just as one makes pariṇāmanā, so one practices giving, and likewise firmly maintains the precepts, with long-term diligence without retreating, and forbearance gentle with mind unmoving"—from "dhyāna concentration" downwards is the same. Here it only takes the text clarifying concentration and wisdom.
