大般涅槃經集解 56.14

56.14

案僧亮曰：因雖無果，而力有近遠，遠名緣因、近名正因，答生有次第也。僧宗曰：謂乳之於酪是正因故，說言有耳，非已有也。寶亮曰：破執既竟，還正義本，謂乳為正因，醪煖作緣因了出酪也。

Sengliang comments: Although the cause contains no fruit, its efficacy has proximity and distance: the distant is called contributory cause, and the proximate is called direct cause; this answers that arising has an order. Sengzong comments: This means that because milk is the direct cause for curd, it is spoken of as existing; it is not that it already exists. Baoliang comments: Having finished refuting the clinging, he returns to the root of the correct meaning, stating that milk is the direct cause, and ferment and warmth act as contributory causes to reveal and bring forth curd.
