法華文句記 3.22

3.22

釋大眾心喜中，先因緣者，昔教奚嘗不覩雨華等相，今欣躍殊常，理應甘露方降，時眾雖無測者，必知機成不久，機感相應何疑不釋。

In explaining the assembly's rejoicing in heart, first regarding cause and condition: in the past teachings, how could they not have witnessed such signs as the raining of flowers? Now their joyful leaping is extraordinary, and in principle the sweet dew [of the Dharma] must be about to descend. Although no one in the assembly at that time could fathom it, they certainly knew that their capacity would soon mature; when capacity and response are attuned to one another, what doubt will not be resolved?
