教觀綱宗 1.22

1.22

頓教部，止用圓、別二種化法；漸教部，具用四種化法。顯露不定，既遍四時，亦還用四種化法。祕密、不定，亦遍四時，亦還用四種化法。頓教相，局惟在圓，通則前之三教，亦自各有頓義，如「善來」得阿羅漢等。漸教相，局在藏、通、別三。通則圓教亦有漸義，如觀行、相似、分證、究竟等。祕密教，互不相知，故無可傳。祕密呪，約四悉檀，故有可傳。不定教、不定益，並入前四時中，故無別部可指。

The sudden teaching corpus employs only two kinds of conversion doctrine: the complete and the distinct. The gradual teaching corpus fully employs all four kinds of conversion doctrine. The manifest indeterminate, pervading the four periods, likewise employs the four kinds of conversion doctrine. The secret and the indeterminate also pervade the four periods and likewise employ the four kinds of conversion doctrine. The characteristics of the sudden teaching are confined strictly to the complete; but in a broad sense, each of the preceding three teachings also has its own sudden meaning, such as attaining the state of an arhat upon [the Buddha saying] "Come, monk!" and the like. The characteristics of the gradual teaching are strictly confined to the three teachings of the Tripiṭaka, shared, and distinct; but in a broad sense, the complete teaching also has a gradual meaning, such as [the stages of] contemplation practice, semblance, partial realization, and ultimate [identity]. The secret teaching cannot be transmitted, because [the recipients] are unaware of one another. Secret mantras, being evaluated according to the four siddhāntas, can therefore be transmitted. The indeterminate teaching and indeterminate benefit are both subsumed under the preceding four periods, so there is no distinct corpus that can be pointed to.
