大乘百法明門論開宗義決 1.246

1.246

此後十種小乘不立隨是六因四緣攝者。四緣之義如上所明。言六因者。俱舍頌云。能作及俱有。同類與相應。遍行并異熟。許因唯六種。廣釋名義如俱舍論。恐文繁廣略而不明。

Regarding "these latter ten kinds are not established by the Hīnayāna; they are subsumed under the six causes and four conditions as appropriate": the meaning of the four conditions is as clarified above. Regarding the six causes, a verse in the Kośa says: "Efficient cause and simultaneous cause, / similar cause and associated cause, / omnipresent cause together with fruition cause: / the admitted causes are only of six kinds." A detailed explanation of their names and meanings is as in the Abhidharmakośa-śāstra; fearing excessive length, it will not be clarified here in brief.
