俱舍論疏 17.6

17.6

論「故於此中至俱極成故」，釋此中業道名通兩類。前七具二，謂業、業道；後三唯一，謂但業道。雖不同類，而一業道名通兩處餘故，兩類總得名為業道。「如世典」者，《正理論》云「世記論也。世記論中亦不同類，而一為餘得通名故。如在天、地類別同名形等。」

On the Śāstra's stating: "Therefore herein [...] because both are thoroughly established", this explains that the name karmapatha here applies to both categories. The first seven possess both—namely, they are both karma and karmapathas; the latter three possess only one—namely, they are karmapathas alone. Although they are not of the same category, a single name, karmapatha, applies to both places due to common usage, and so both categories together receive the name karmapatha. As for "like worldly scriptures", the Nyāyānusāra states: "Worldly chronicles (lokāyata). In worldly chronicles as well, they are not of the same category, yet one serves to share a common designation with the other; just as in heaven and on earth, distinct categories share the same name 'form' and so forth."
