大方廣佛華嚴經隨疏演義鈔 58.26

58.26

From the commentary's "fourth, with a single sound" downward: this activity expounds all at once with a single sound, hence it is called "various." The meaning of a single sound was already explained in the earlier commentary, and will be expounded further below. Stating "because it accords with their spiritual capacity": this explains the sūtra's words "causing joy"; because it accords with capacity, they rejoice. The commentary's "activity of not severing the Buddha seed": because transformation after transformation never ceases. This activity is expounded extensively in the section on nirvāṇa in the "Chapter on Manifestation."
