俱舍論疏 13.147

13.147

論「若身、語業至無漏生故」，此釋無漏隨生處也。若無漏者，依五地身，隨生此地應起現前，即用此地四大所造，以無漏法不繫界故。所以不用同地大造，必無大種是無漏故。無無漏大造無漏色，由所依力無漏生故，即用彼隨身四大所造。

The treatise says: "If physical and vocal actions... down to: because the uncorrupted arises." This explains that the uncorrupted (anāsrava) accords with the place of birth. If it is uncorrupted, it relies on the bodies of five planes; according to where one is born and should give rise to its manifestation, it is produced precisely by the four primary elements of that plane, because uncorrupted dharmas are not bound to any realm. The reason it is not produced by the primary elements of the same plane is that there are certainly no primary elements that are uncorrupted. There are no uncorrupted primary elements to produce uncorrupted forms; because the uncorrupted arises by the power of the support, it is produced precisely by the four primary elements of the body it accompanies.
