維摩經略疏垂裕記 3.121

3.121

四、精進。「但約眾行」者，謂勤修五度得精進名。「自有別體」者，謂誦經禮佛為精進也。「謂正勤」者，勤斷二惡、勤生二善並屬精進，故以此四并根力覺道為八。此還就初義明精進也。

Fourth, vigor. Regarding "only in terms of the various practices": this means that diligently cultivating the five perfections receives the name "vigor." Regarding "having its own distinct essence": this means reciting sūtras and bowing to the Buddha constitute vigor. Regarding "namely, right exertion": diligently severing the two evils and diligently producing the two goods both belong to vigor; hence, with these four together with faculties, powers, factors of awakening, and the path, they make up the eight. This again clarifies vigor in terms of the initial meaning.
