摩訶止觀 7.113

7.113

答：此有三句：六度破道品，道品破六度；六度修道品，道品修六度；六度即道品，道品即六度。如上道品不能契真，若修六度即能破蔽，豈非六度破道品？有時六度不能到彼岸，若修道品即得悟入，是為道品破六度。若修六度，先破六蔽，進修道品，任運可成，是為六度修道品。如上所說，即是道品修六度。六度道品相即者，檀即摩訶衍，四念處亦即摩訶衍，檀與道品無二無別，不可得故。通論諸法，於行無益，互有相破；於行有益，互有相修；約理，互有相即。若四諦因緣有、無、非有無，廣歷一切法皆有三番。若得此意，自在說（云云）。

Answer: Here there are three propositions: the six perfections destroy the factors of the Way, and the factors of the Way destroy the six perfections; the six perfections cultivate the factors of the Way, and the factors of the Way cultivate the six perfections; the six perfections are identical to the factors of the Way, and the factors of the Way are identical to the six perfections. As stated above, if the factors of the Way cannot accord with reality, if one cultivates the six perfections one can destroy the veils—is this not the six perfections destroying the factors of the Way? At times the six perfections cannot reach the other shore, but if one cultivates the factors of the Way one attains awakening—this is the factors of the Way destroying the six perfections. If one cultivates the six perfections, first breaking the six veils and then advancing to cultivate the factors of the Way, it can be naturally accomplished—this is the six perfections cultivating the factors of the Way. As stated above, this is the factors of the Way cultivating the six perfections. As for the six perfections and factors of the Way being mutually identical: giving is Mahāyāna, the four smṛtyupasthānas are also Mahāyāna; giving and the factors of the Way are non-dual and without distinction, because they are ungraspable. Speaking generally of all phenomena: when not beneficial to practice, they mutually negate each other; when beneficial to practice, they mutually cultivate each other; in terms of principle, they are mutually identical. If the four noble truths and conditioned arising—existence, non-existence, and neither existence nor non-existence—are extensively applied across all dharmas, there are three rounds for each. If one grasps this meaning, one can expound freely, and so forth.
