成唯識論了義燈 1.36

1.36

As the Nirvāṇa Sūtra, fascicle twenty-four, says: 'Expounding a single dharma, whether a realm or an entrance, all sentient beings hear it each according to their original understanding.' This is an expounding of doctrine and phrasing combined. In a single phrase and sentence, many phrases and sentences appear; in a single sound, many sounds appear; therefore, each follows their original understanding, subsuming the provisional into sound. Because the various phrases and sentences differ according to the beings, yet are not separated from sound, it is collectively called 'hearing'. Furthermore, the Brahmajāla says in its first part: 'In a single voice, expounding immeasurable categories of dharmas.' It also says: 'Suffering, emptiness, impermanence, non-self: the sound of the single truth.' Both combine doctrine and phrasing. Or it only cites doctrine, as the Avataṃsaka says: if there are many defilements such as greed and anger, the eighty-four thousand impurities, each hears the counteracting dharma. It also says: 'Expounding the Dharma with a single voice.' Or there are sentient beings who study the Śrāvakayāna, and hearing the Buddha expound the Dharma, immediately understand the Śrāvaka Piṭaka. These merely explain the unobstructedness of doctrine, but also apply to phrasing, for hearing means hearing sound.
