摩訶止觀 3.189

3.189

就此為五：一、明大小，二、明半滿，三、明偏圓，四、明漸頓，五、明權實。夫至理不大、不小，乃至非權、非實。大、小、權、實皆不可說。若有因緣，大、小等皆可得說。以小方便力，為五比丘說小；以大方便力，為諸菩薩說大。大小雖俱方便，須識所以，故用五雙料簡，使無混濫。

Regarding this, there are five [topics]: first, clarifying Hinayāna and Mahāyāna; second, clarifying the half and the full; third, clarifying the biased and the perfect; fourth, clarifying the gradual and the sudden; fifth, clarifying the provisional and the real. The ultimate principle is neither large nor small, and so on up to neither provisional nor real. Large and small, provisional and real, are all ineffable. Given conditions, large, small, and so on can all be expounded. Through the power of small expedient means, he expounded the Hinayāna for the five monks; through the power of great expedient means, he expounded the Mahāyāna for the bodhisattvas. Although both large and small are expedient means, one must understand their rationale; therefore we use five pairs of distinctions so that there is no confusion.
