金光明經文句記 4.154

4.154

二、「若果」下，結由集業。經舉四大升沈尤甚，正明集境善惡殊塗，以其四大不獨是惡亦通漏善也。

Second, from "If the fruit" downward, concluding that it is due to the karma of origination. The sūtra adduces the rising and sinking of the four great elements as especially prominent, directly clarifying that in the object of origination, good and evil follow different paths, because the four great elements are not only evil, but also extend to tainted goodness.
