大方廣佛華嚴經隨疏演義鈔 63.77

63.77

疏「道言無二」者，略牒經文，具云「出生無二故」。論經云「起不二行故」。既稱滅知，故不生二行。

Regarding the commentary's "the path is said to be non-dual," this briefly cites the sūtra text, which fully states, "because it produces non-duality." The treatise sūtra states, "because it gives rise to non-dual practice." Since it is termed knowing cessation, it does not generate dual practice.
