4.41

Regarding "The obscured has eighteen": this takes the obscured indeterminate mind of the desire realm, namely that which is associated with the two views of individuality and extremes. These two kinds of view can obscure the noble path, or are obscured by delusion, hence called "obscured"; and because they cannot yield a [karmic] maturation, they are called "indeterminate". This obscured mind must have eighteen mental factors co-arising, namely the ten great ground [factors], the six great defilement ground [factors], as well as investigation and scrutiny. That a view is not added here should be understood as explained above.
