瑜伽論記 2.294

2.294

起執緣理中，具正方便，而招於苦，具邪方便，而致於樂知，由宿作者，若爾，云何前說現法方便所招之苦？復云：由勤精進吐舊業等，解云：彼人但據感報正因必是宿業，故名宿作。復說由現苦行能吐宿惡，由此後句被論家破。

In the rationale for the arising of the clinging, knowing that possessing correct means brings about suffering, while possessing false means leads to pleasure, is due to past deeds: If so, why was it said earlier that suffering is brought about by the means of the present life? And further said: "through energetic striving, old karma is purged," and so forth? The explanation is: That person only relies on the primary cause of receiving retribution necessarily being past karma, and therefore it is called "past deeds." Furthermore, it is said that through present ascetic practices one can purge past evil; hence this latter clause is refuted by the author of the treatise.
