俱舍論記 6.15

6.15

「此難不然至有親作力」者，釋難。但由無障，許一切法為能作因，非由於果生，有餘五因親作力故，所以諸法非皆頓起。非由於殺，生有因等起親作力故，所以非如殺者皆成殺業。

Regarding '[This objection is not valid ... has direct productive efficacy]', this resolves the objection: It is only by virtue of being unobstructed that all dharmas are acknowledged as efficient causes; it is not that they have the direct productive efficacy of the other five causes with respect to the arising of the fruit; hence, dharmas do not all arise simultaneously. Nor is it that, with respect to killing, they have the direct productive efficacy arising from an intention to kill, etc.; therefore, they are not like the killer, all constituting the karma of killing.
