成唯識論述記 2.180

2.180

述曰：此第三發身、語思有所造作，謂於境轉造作於心，復能發身、語，故名為業。道有二義：一者，是前審、決二思所遊履故，謂第三思為前二思所遊履故，即是所緣所引發義，如身、語是思所遊等。二者，或通生當來苦樂異熟，故亦名道。思道名亦亦於業也，非唯名業，亦名道故。又亦身、語二，非唯身、語名道，思但名業，即是身、語亦得名業，思亦名道。道者，依止義，依之進趣生當果故。十業道中前七之思，為後三種業所履故，意業能生當異熟故，是其道義。

The Commentary states: This third volition, which activates bodily and vocal action, possesses activity—that is, it transforms in relation to an object and acts upon the mind, and further can activate body and speech; therefore, it is called karma. "Path" has two meanings: First, it is that which is traversed by the preceding two volitions of deliberation and resolution; that is, because the third volition is traversed by the preceding two volitions, it has the meaning of an object of cognition and that which is induced, just as body and speech are that which is traversed by volition, and so forth. Second, or alternatively, it leads to the production of future ripening (vipāka) of suffering and pleasure; therefore, it is also called a path. Volition being called a path also applies to karma; it is not only called karma, but also called a path. Moreover, [this applies] also to the two of body and speech: it is not only that body and speech are called paths while volition is only called karma; that is to say, body and speech also attain the name of karma, and volition is also called a path. "Path" means support, because relying on it one advances toward and generates a future fruit. Among the ten paths of karma, because the volition of the first seven is traversed by the karma of the latter three, and because mental karma can generate future ripening, this is its meaning of "path".
