俱舍論疏 6.98

6.98

論「本論唯說至故無有失」，此是不正義家，通本論中不說難也。本論唯說取、與果因，未來無取、與故，所以不說。

The treatise says: "The root treatises only speak... therefore there is no fault." This is the incorrect proponent resolving the objection that the root treatises do not speak of it. The root treatises only speak of causes that take and give fruit; because there is no taking and giving in the future, they do not speak of it.
