法華玄論 7.64

7.64

答：有人言唯一法身，法身不二故名為一。從一法身出音，以法身為名故云一音也。評曰：《大品》釋相好云「以一音報眾聲」，不明法身，故非解也。有人言：一時中竝出眾音，故云一音也。評曰：經但云一音，不云眾音並出，亦非所用。有人言：身為天竺之身，音為天竺之音，故云一音。評曰：佛能隨咄一音，非局天竺。又有人言：五音之中隨用一音。評曰：佛既託一方之迹、受一土之音，五音義通，亦非所用也。今所明者，此義多含，略明四種：一者依〈藥草品〉明一大雲普覆、一大雨遍洽，喻一乘大法音，故名一音。但大緣悟大，故稱於大；小緣悟小，小不稱為大，故一音之名主一大乘音也。

Answer: Some say it is solely the single dharmakāya; because the dharmakāya is non-dual, it is called single. The voice issues from the single dharmakāya, and taking its name from the dharmakāya it is called a single voice. Appraisal: The Pañcaviṃśatisāhasrikā, in explaining the physical marks, says: 'With a single voice responding to all sounds'; it does not clarify the dharmakāya, so this is not the explanation. Some say: within a single time multiple sounds issue forth together, hence it is called a single voice. Appraisal: The sūtra merely says a single voice, and does not say that multiple sounds issue forth together; this too is not to be adopted. Some say: the body is an Indian body, and the voice is an Indian voice, hence it is called a single voice. Appraisal: The Buddha is able to utter a single voice as appropriate, not restricted to India. Yet others say: among the five tones, he uses any one tone as appropriate. Appraisal: Since the Buddha relied on the traces of a particular region and received the sounds of a particular land, the meaning of the five tones applies generally; this too is not to be adopted. What is clarified now is that this meaning contains many aspects; we briefly clarify four kinds: First, relying on the 'Chapter on Medicinal Herbs', it clarifies that one great cloud covers universally and one great rain soaks everywhere, which is an analogy for the great Dharma voice of the One Vehicle, and hence is called a single voice. But those with great capacities awaken to the great and thus correspond to the great; those with small capacities awaken to the small, and the small is not called great, so the name 'single voice' primarily refers to the voice of the One Great Vehicle.
