十不二門指要鈔 2.20

2.20

問：「十種三法俱通修性，各可對三德三因。何故三般若等唯對了因，三菩提等獨對緣因？」

Question: "The ten kinds of three dharmas all apply to both cultivation and nature, and each can correspond to the three virtues and three causes. Why do the three prajñās and so forth correspond exclusively to the revealing cause, while the three bodhis and so forth correspond solely to the conditioning cause?"
