大般涅槃經集解 8.52

8.52

案僧宗曰：猶是明第二重顯於見性善業之終也。寶亮曰：此第十第十一兩問廣因，下〈如來性品〉答也，作善行是緣因。前所以答中明正因者，欲明行人立心之方。若明識因果性者，則行成中道。若中道行成，則萬善便樹。故答以正因中道行即緣因也。智秀曰：第十二問何地大士能照當果性之理也。

Sengzong states: This is still clarifying the second stage, manifesting the culmination of good karma in seeing the nature. Baoliang states: These two questions, the tenth and eleventh, expand upon the cause, and are answered below in the 'Chapter on the Tathāgata Nature.' Performing good practices is the contributory cause. The reason the direct cause was clarified in the preceding answer was to illuminate the practitioner's method of establishing the mind. If one clearly recognizes the nature of cause and fruition, one's practice will accomplish the Middle Way. If practice of the Middle Way is accomplished, the myriad goods are established. Thus, answering with the direct cause, the Middle Way practice is itself the contributory cause. Zhixiu states: The twelfth question asks which stage of Great Being can illuminate the principle of the future fruition-nature.
