然觀本意，後解是本，今難本意。由是義顯，應諸現行望本有種不名因緣，熏增長故，此本有種唯以自類為其因緣。既爾，此因應不生現，有新起種生故，此義應思。然以生種類同於新，亦因緣攝，不同唯本有，故彼非因緣。

Yet, looking at the primary intent, the latter explanation is the primary one, which now challenges their primary intent. By this the meaning is evident: all actualities should not be called cause and condition with respect to originally existent seeds, because they merely perfume and augment them; these originally existent seeds would take only their own kind as their cause and condition. If so, this cause should not generate actuality, for it is newly arisen seeds that generate it. This point should be considered. However, because generating seeds belongs to the same class as newly arisen ones, it is also included under cause and condition; unlike [the thesis of] only original existence, therefore that [position] lacks cause and condition.
