俱舍論疏 6.155

6.155

The treatise says: "In the desire realm, [...] and their arising and so forth." From here below, it clarifies, with respect to the realms, the number of aggregates serving as cause that induce fruits. In the desire realm, one aggregate alone is an acquisition (prāpti) that induces one fruit, because acquisition and arising and so forth belong to the same aggregate of conditioned factors (saṃskāra-skandha).
