四分律刪繁補闕行事鈔 1.237

1.237

餘之正法，乃至心念，當法自成，不相通練。別眾一法，多或通之，廣張非相，如《義鈔》也。

The remaining correct rites, down to mental acts, are accomplished each within its own rite and do not interpenetrate or apply across [all others]. The single rule concerning a separate saṃgha, however, is mostly applicable across them; for a broad exposition of its invalid characteristics, see the Yichao (Commentary on the Meaning).
