大方廣佛華嚴經疏 51.41

51.41

第八「十種辯才」下二門，明童真住中行。此門即自分行，由三業無失故，有無著辯。由知眾生欲解，故辯令他喜。後門即彼勝進，現變化自在身等，皆自在義。

Eighth, from 'ten kinds of eloquence' onward, two gates clarify the practice in the stage of the kumārabhūta. This gate is the practice within its own station: because the three karmas are without fault, one has unattached eloquence. Because of knowing the desires and understandings of sentient beings, one's eloquence causes others to rejoice. The latter gate is that station's superior progress: manifesting bodies of sovereign transformation, etc., which all have the meaning of sovereignty.
