成唯識論掌中樞要 2.13

2.13

Among the analogical extensions of mental factors, the third master says: they are analogously extended according to six meanings. Now, observing the fourth master's refutation, he does not extend them analogously to discernment and co-occurring with sensation, but extends them analogously to six categories. Although there is the objection that contact co-occurs with contact, allowing the five dharmas to co-occur serves as the basis for the analogical extension. In all three explanations, that which an arhat does not relinquish as storehouse afterward, where only the primary mind (citta) relinquishes the storehouse, serves as the reason for mental factors not relinquishing the storehouse. The earlier analogical extensions are like this; otherwise, why make an analogical extension midway? Thus, relying on the first two explanations is correct, along with the fourth explanation.
