問：人聞則人音、天聞則天音，而音非人非天者，亦應一緣聞則音一、多緣聞則音多，而音非一非多也。

Question: If when humans hear it, it is a human voice, and when devas hear it, it is a deva voice, yet the voice is neither human nor deva, then likewise when a single condition hears it, the voice is single, and when multiple conditions hear it, the voice is multiple, yet the voice is neither single nor multiple.
