大方廣佛華嚴經隨疏演義鈔 64.31

64.31

疏「由前觀察隨順得至不住道」者，故論經云「是菩薩如是觀一切法隨順得至」，論釋云「得至不住道行勝故」。今經略無隨順得至之言，而言如是觀已，意則合有，故疏取論攝前釋之。

On the commentary passage "Through the previous contemplation, conforming and attaining the unabiding path": hence the sūtra text of the treatise says, "This bodhisattva contemplates all dharmas in this way, and conforming, attains..."; the treatise's explanation says, "because attaining the practice of the unabiding path is excellent". The present sūtra is concise and lacks the words 'conforming and attaining', but says 'having contemplated thus'; in meaning, it must contain them, so the commentary takes the treatise, subsumes what came before, and explains it.
