俱舍論疏 6.4

6.4

論「且因六種」，文中有二：一六因、二四緣。緣次後說，先釋因故，故言且因六種。

On the Śāstra's statement: "First, causes are of six kinds": within the text there are two parts: first, the six causes; second, the four conditions. Because conditions are explained right afterward and causes are explained first, it therefore says: "First, causes are of six kinds."
