俱舍論疏 6.309

6.309

論「有覆無記至如理應說」，釋有覆無記四句也。於阿羅漢得時取而不與，退時與而不取，未得亦取亦與，自餘非取非與。

On the Śāstra's: "Obscured indeterminate […] up to: should be stated in accordance with the principle": this explains the four alternatives regarding obscured indeterminate [dharmas]. At the time an arhat attains [arhatship], they grasp but do not give; at the time of retrogression, they give but do not grasp; when not yet attained, they both grasp and give; all others neither grasp nor give.
