7.247

第三番明前二正斷若行過未境界如是行時不令煩惱緣彼生起設暫時起速能斷滅，名策勵。若行現在不令煩惱緣彼生起設記速滅，名發勤精進。

The third round explains that regarding the first two correct abandonments, if one operates on past and future spheres of experience, and when operating thus one does not allow the afflictions to arise taking them as objects, and even if they temporarily arise, one is able to swiftly cut them off: this is called “exerting effort.” If, when operating on the present, one does not allow afflictions to arise taking it as an object, and even if [they arise] one swiftly extinguishes them: this is called “putting forth energetic striving.”
