大方廣佛華嚴經疏 1.28

1.28

第九依請人者，若約慈悲深厚，亦有無問自談；若約敬法重人，要須誠請後說。初心識昧，未解諮求；上智慈悲，騰疑啟請。然有二類：一者言請、二者念請。諸會有無，〈現相品〉當辯。

Ninth, relying on the requester. In terms of profound benevolence and compassion, there is also speaking without being asked; in terms of revering the Dharma and respecting persons, it is necessary to preach only after a sincere request. Those with beginner minds have obscure understanding and do not know how to inquire; those of superior wisdom, out of compassion, voice doubts and initiate the request. There are two kinds: 1. verbal requests, 2. mental requests. Their presence or absence in the various assemblies will be analyzed in the 'Chapter on the Manifestation of Signs'.
