俱舍論疏 17.5

17.5

論「前七是業至立業道名」，釋前七業道。前七業道是業性故，名之為業；思業依託為境轉故，名業道也。此七是業、是業之道，立業道名。

On the Śāstra's stating: "The first seven are karma [...] the name karmapatha is established", this explains the first seven karmapathas. Because the first seven karmapathas are of the nature of karma, they are called karma; and because karmic volition operates by taking them as its objective support, they are called karmapathas. These seven are karma and are the path of karma, so the name karmapatha is established for them.
