法華論疏 1.261

1.261

釋因中有二因：一正因、二緣因。正因者謂一切智，以因一切智能見過去世事相也。又緣因成就謂眾相者，釋第二緣因也。言眾相者，謂動地、雨華、放光名為眾相。由見過去世佛現於眾相故現大法，今見釋迦現眾相亦說大法，故眾相為說法之因也。

In explaining the cause, there are two causes: first, the direct cause; second, the auxiliary cause. The direct cause refers to all-knowledge; because of all-knowledge, one can see the events and marks of past ages. Furthermore, 'the auxiliary cause being complete refers to the manifold signs' explains the second, auxiliary cause. The term 'manifold signs' refers to the shaking of the earth, the raining of flowers, and the emitting of light being called manifold signs. Because past Buddhas, having manifested the manifold signs, manifested the great Dharma, now seeing Śākya[muni] manifest the manifold signs, he will likewise preach the great Dharma; thus the manifold signs are the cause of preaching the Dharma.
