15.37

解有行中，且如眼識心及心所同取一本質境，各於一所緣起多行解，各變相分當自心起，名無量種行相而轉。

In explaining 'having active modes' [ākāra]: for instance, the eye-consciousness and its mental factors together apprehend the same fundamental object (bimbālambana), but each gives rise to multiple active understandings with respect to the one cognitive object, each manifesting an objective aspect (nimittabhāga) that arises within its own mind; this is called proceeding with immeasurable kinds of active modes.
