因明入正理論疏 3.21

3.21

問：「於因三相是何過耶？」答：「彼立因意，成非積聚他用勝，其積聚他用勝即是異品，宗無同喻。佛法都無不積他故，積聚性因於異品有。此顯還是九句之中異有同無，故成相違，闕第二相同品定有，亦闕第三異品遍無。」

Question: 'Regarding the three characteristics of the reason, what fault is it?' Answer: 'His intention in putting forward the reason is to establish that the use by a non-composite other is primary. The primary use by a composite other is the heterologue (vipakṣa); the thesis has no homologous example (sapakṣa). In the Buddha's teaching there is no non-composite other whatsoever; therefore, the reason "being composite" is present in the heterologue. This shows that it still belongs to the case among the nine types of reason where it is present in the heterologue and absent from the homologue; hence it becomes contradictory, lacking the second characteristic, definitive presence in the homologue, and also lacking the third characteristic, pervasive absence from the heterologue.'
