天台八教大意 1.45

1.45

故知中下修觀，十法具須。上根體境含諸，或一、二、三不定，內外作受無不咸然。大車無量，言豈徒設？以法對譬出自一家，本迹所歸，圓理無二。不別而別，位位增明，廣如餘文，非此可具。依文判義，若四若八目擊道存。

Hence we know that when those of medium or inferior capacity cultivate contemplation, all ten dharmas are necessary. Those of superior capacity realise the object as encompassing them all, or [rely upon] one, two, or three indeterminately, and internal or external acts and experiences are invariably so. The great carriage is immeasurable; could its description have been set forth in vain? Matching the Dharma to the metaphor originated within our own tradition; as that to which the origin and traces return, the perfect principle is not two. Without differentiating yet differentiated, it increases in clarity rank by rank; this is extensively [treated] in other texts and cannot be fully presented here. Judging the doctrines according to the texts, whether the four [teachings] or the eight [teachings], the Way is present before one's very eyes.
