大乘百法明門論開宗義決 1.64

1.64

若異心等等者。此中量云。不相應行定非實有。宗也。心心所色及諸無為所不攝故。因也。如畢竟無。喻也。畢竟無者。即龜毛等畢竟無。心等不攝。畢竟無非是實有。不相應心等不攝。不相應亦非實有。

Regarding 'If they were distinct from mind and the rest', and so forth: in this inference, the thesis is: 'Non-associated formations are definitely not real existents.' The reason is: 'Because they are not subsumed under mind, mental factors, form, or unconditioned dharmas.' The example is: 'Like absolute nonexistence.' 'Absolute nonexistence' refers to things like the hair of a turtle, which are absolutely nonexistent and not subsumed under mind and the like. Absolute nonexistence is not a real existent; non-associated [formations] are not subsumed under mind and the like, so non-associated [formations] are also not real existents.
