仁王護國般若波羅蜜多經疏 3.242

3.242

解行名者，精懃修習，心不退亂，名無屈撓行，以懃三業為自性也。利自他者，遍策諸根修諸勝行，皆不退屈，能益自他。精進行也。從此第五離癡亂行。

Explaining the name of the practice: Diligently cultivating, the mind neither regresses nor is distracted, so it is called the practice of non-yielding; the three karmas of diligence are its intrinsic nature. "Benefiting oneself and others": universally prompting all faculties to cultivate superior practices without regressing or yielding, able to benefit oneself and others. This is the practice of vigor. From here, the fifth is the practice of freedom from delusion and confusion.
