「有說餘因至異熟不爾」者，答中有二，此即初師。餘同類、遍行、能作三因亦有士用果，唯除異熟因。由士用果總有二種：一與因俱生、二與因無間。相應、俱有能取俱生。同類、遍行、果若相隣，能取無間。能作通取俱生、無間。故此五因得士用果。異熟因不爾，與果性異感果稍難，要因相續果乃現前，非俱、無間，故無士用。又解：異熟果不爾，非與因俱、無間，故非士用。

Regarding "Some say the other causes ... maturation is not like this": within the answer there are two [positions], this being the first master. The other three causes—homogeneous, omnipresent, and efficient—also have the fruit of human effort, with the sole exception of the cause of maturation. Because the fruit of human effort has two types in total: first, arising simultaneously with the cause; second, arising immediately after the cause. Associated and simultaneous [causes] can take what arises simultaneously. For homogeneous and omnipresent [causes], if the fruit is adjacent, they can take what is immediately contiguous. The efficient [cause] generally takes both simultaneous and contiguous. Therefore these five causes obtain the fruit of human effort. The cause of maturation is not like this: being of a different nature from the fruit, producing the fruit is rather difficult, requiring a continuum for the fruit to become manifest; not being simultaneous or immediately contiguous, it therefore lacks [the fruit of] human effort. Another explanation: the fruit of maturation is not like this, not being simultaneous or immediately contiguous with the cause, hence it is not [the fruit of] human effort.
