3.866

若不言餘簡異熟心，而但說云非佛有情應起異熟，此便相扶，他亦有起異熟心故。又由不簡餘異熟心，便在宗中不可取宗而以為喻，故闕喻失。

If one did not use 'other' to exclude maturation-minds, but merely said 'sentient beings other than Buddhas should produce maturation,' this would prove what is already accepted (siddhasādhana), since the other party also accepts the arising of maturation-minds. Furthermore, by not excluding other maturation-minds, [the subject] remains within the thesis and cannot be taken from the thesis to serve as an example; thus there is the fault of lacking an example.
