俱舍論疏 1.192

1.192

論「為簡諸得至大種所造」，此第四述無表因也。得雖四位，相似相續與無表同，非四大造與無表異。即以造因簡於諸得，復言大種所造。

The Śāstra says: "In order to exclude acquisitions... derived from the primary elements." This is the fourth section, which states the cause of the unmanifest. Although acquisitions [occur in] four states and resemble each other in continuation just like the unmanifest, they are not derived from the four great elements and thus differ from the unmanifest. Thus, using the cause of derivation to exclude acquisitions, it further states: "derived from the primary elements."
