大方廣佛華嚴經隨疏演義鈔 63.63

63.63

疏「智清淨等無癡亂故」者，即下經文云「十重觀察四諦法門，名智清淨。」正是無癡，知第一義。如實而知，即無亂義。而言等者，等取利益眾生勤方便勝，皆無癡義，與彼行中釋於無癡義甚相順。

As for the Commentary saying, "Because wisdom-purification and so forth are free from delusion and confusion": this refers to the lower sūtra text which says, "The tenfold contemplation of the Dharma-gate of the four truths is named wisdom-purification." This is precisely freedom from delusion, knowing the ultimate truth. Knowing according to reality is precisely the meaning of freedom from confusion. As for saying "and so forth": it encompasses the excellence of diligence and upāya in benefiting sentient beings; these are all the meaning of freedom from delusion, and accord very closely with the explanation of freedom from delusion in that practice.
