俱舍論疏 15.158

15.158

論「業與樂受至利益樂受」，此第一通難也。業之與受體性雖殊，而能為因引樂受生，故名為順受。資助令生，名為利益。

On the Śāstra's statement: "Action [acts] upon pleasant sensation [...] benefits pleasant sensation": This is the first resolution of the objection. Although the essential natures of action and sensation differ, [action] can serve as a cause to induce the arising of pleasant sensation; hence it is called "conducive to sensation." Assisting and causing it to arise is called "benefiting."
