俱舍論記 15.125

15.125

「論曰至善不善故」者，如是安等業名善等業相，謂安穩業說名為善。能得可愛異熟果者，暫時濟眾苦故。能得可愛涅槃果者，永時濟眾苦故。不安穩業名為不善，由此能招非愛異熟，又極遮止趣向涅槃，與前安穩性相違故。非前二業，立無記名，無別勝能，不可記為善、不善故。

Regarding 'The commentary says ... to ... wholesome and unwholesome': such karmas that are secure and so forth are the characteristics of wholesome and other karmas; that is, secure karma is termed wholesome. One that can obtain a desirable vipāka fruit rescues one temporarily from manifold sufferings; one that can obtain the desirable nirvāṇa fruit rescues one eternally from manifold sufferings. Insecure karma is termed unwholesome, because it brings about undesirable vipāka, and also severely obstructs progress toward nirvāṇa, being contrary in nature to the aforementioned security. Karma that is neither of the preceding two is designated by the name indeterminate (avyākṛta), because it has no distinct, superior capacity and cannot be determined as wholesome or unwholesome.
