摩訶止觀 7.124

7.124

是一法門而有四種者，如王密語，智臣解意。佛說十力赴四種機，不令小者謗大，傷其功德；不令大者得小，抑其善根。彼彼獨聞，各各獲利，無謀權巧，故號「能仁」。菩薩智臣深解密語，知意在三藏，即問生滅，鄭重諮詢，令有緣疾悟；乃至知意在圓，或頌無作，或問無作，令他得解。一音殊唱，萬聽咸悅，口密無邊，義不可盡。上作四釋，何足致疑耶？

That there are four kinds within this single Dharma-gate is like a king's secret words, where a wise minister understands the intention. The Buddha taught the ten powers to respond to four kinds of capacities: not letting the lesser disparage the great and harm their merit; not letting the great grasp the lesser and suppress their wholesome roots. Each hearing privately, each obtains benefit, without deliberate contrivance or calculated skill, and thus he is called the "Benevolent One" (Śākyamuni). Bodhisattvas, as wise ministers, deeply understand the secret words: knowing the intention lies in the Tripiṭaka [teaching], they ask about origination and cessation, inquiring earnestly so that those with conditions may swiftly awaken; so too, knowing the intention lies in the perfect [teaching], they either praise the unconditioned or inquire about the unconditioned to cause others to gain understanding. A single voice singing diversely pleases myriad listeners; the verbal secret is boundless, and its meanings inexhaustible. Why should making the four interpretations above give rise to any doubt?
