「論曰至四不共事」，第五釋頌文也。於中有三：初釋五根有四增上、次釋四根各二增上、後釋十三根各一增上。此即列四增上用也。

On: "The commentary says: […] four uncommon activities": this is the fifth [section], explaining the text of the verse. Within it there are three parts: first, explaining that the five faculties have four kinds of predominance; next, explaining that four faculties each have two kinds of predominance; and last, explaining that thirteen faculties each have one kind of predominance. This, then, lists the four predominant functions.
