大方廣佛華嚴經疏 6.25

6.25

九中，法門無邊，出者為要，根器萬品故出要難思。此於著相得解脫。

In the ninth, the Dharma approaches are boundless, and those for deliverance are essential; because capacities are of ten thousand kinds, the essential ways of deliverance are difficult to conceive. This attains liberation from attachment to marks.
