華嚴經明法品內立三寶章 2.16

2.16

二、利益者，若依小乘，如來言音未必一切皆有利益，如佛問阿難天雨等，非是法輪音聲所攝。若大乘等中，如來所發世俗言音，無不皆成大利益故，如佛入城唱乞食聲，令城同聞，俱獲利益，故經云：「諸佛音聲語言、威儀進止無非佛事。」

Second, regarding benefits: If one relies on the Hīnayāna, the Tathāgata's vocal sounds do not necessarily all have benefit, as when the Buddha asked Ānanda about rain from the sky and the like, which are not subsumed under the sounds of the wheel of Dharma. If in the Mahāyāna and the like, none of the worldly vocal sounds emitted by the Tathāgata fails to accomplish great benefit; as when the Buddha entered the city chanting the call for almsfood, causing the whole city to hear it together and all obtain benefit. Thus the sūtra says: 'The sounds, speech, deportment, moving, and resting of all Buddhas are nothing other than Buddha-work.'
