2.21

三、出因者，有四：一者了因，照現本有真如法故。二者生因，生成修起勝功德故。三者生、了無礙因，生、了相即，二果不殊故。四者總此勝德為所依因，印機現用為所成果。

Third, specifying the causes: There are four. The first is the illuminating cause (jñāpaka-hetu), because it illuminates and manifests the fundamentally existent dharma of tathatā. The second is the productive cause (kāraka-hetu), because it generates and brings forth through cultivation supreme qualities. The third is the unobstructed cause of generation and illumination, because generation and illumination are mutually identical, and the two fruits are not different. The fourth is taking all these supreme qualities as the basis-cause, with the manifestation of functions in imprint to capacities being the resulting fruit.
