華嚴經探玄記 3.37

3.37

五明法輪分齊者，若小乘中，有一義：佛說四諦苦無常等語音，入法輪攝；如問阿難天雨等如是世語，皆非法輪。若三乘中，佛一切語及身威儀皆入法輪，以無不益生故。《維摩經》云「諸佛威儀進止無非佛事。」以此准之。若一乘中，通三世間俱入法輪，一切眾生語言音聲亦入法輪。國土法輪如剎說等准之。

Fifth, clarifying the limits of the dharmacakra: in the Hinayana, there is one view: the words and sounds of the Buddha preaching the four truths, suffering, impermanence, and so forth, fall within the purview of the dharmacakra; mundane speech such as asking Ānanda whether it is raining is not the dharmacakra. In the three vehicles, all words of the Buddha and the bodily deportments all fall within the dharmacakra, because there is none that does not benefit sentient beings. The Vimalakīrti-sūtra states: "The deportment and actions of all Buddhas are nothing other than Buddha-works." Rely on this as the standard. In the One Vehicle, all three realms universally fall within the dharmacakra; all spoken languages and sounds of sentient beings also fall within the dharmacakra. The dharmacakra of lands is understood by analogy with the preaching of lands and so forth.
