大方廣佛華嚴經疏 6.44

6.44

七一切等者，通有二義：一現多身、興多供、供多佛，皆稱真故，名大方便，即長行意；二一念八相遍法界故，名大方便，即偈中意。於上自在，名為解脫。

In the seventh, "all," and so on, broadly has two meanings: first, manifesting many bodies, raising many offerings, and offering to many Buddhas, all matching reality, is called great skillful means, which is the meaning of the prose; second, in a single thought the eight marks pervade the dharmadhātu, which is called great skillful means, which is the meaning of the verse. Mastery over the above is called liberation.
