問：「四相違九句，何句所攝？」答：「乍觀文勢，唯初一違是九句中第四、第六，具二因故，九中二因違法自相相違因故。今觀後三皆彼第四，同品非有、異品有故，違所立故。此上所說，但是立敵兩俱不成四相違因，亦有隨一、猶預、所依餘三不成四相違因。三十六中一一有四，合計一百四十四種諸相違因。如不定中引《理門》說，皆應思惟，恐文繁雜故略不述。然《理門論》攝此頌云：『邪證法有法，自性或差別，此成相違因，若無所違害。』」

Question: "Under which clauses among the nine clauses [of the wheel of reasons] are the four contradictory reasons subsumed?" Answer: "At first glance at the trend of the text, only the first contradiction is the fourth and sixth among the nine clauses, possessing both reasons, because two reasons among the nine contradict the reason contradicting the property's svabhāva. Now observing the latter three, all are the fourth clause, because they are absent from the sapakṣa and present in the vipakṣa, contradicting what is to be established. What has been discussed above are only the four contradictory reasons of both parties unproved (ubhaya-asiddha); there are also the four contradictory reasons of any-one unproved (anyatara-asiddha), doubtful unproved (saṃdigdha-asiddha), and unproved locus (āśraya-asiddha). Among the thirty-six, each has four, totaling one hundred and forty-four contradictory reasons. As quoted from the Nyāyamukha under inconclusive reasons, all should be reflected upon; fearing that the text would become complex, they are briefly omitted. However, the Nyāyamukha summarizes this in a verse: 'Perversely proving the property or the subject, / Their intrinsic nature or their distinction, / This constitutes a contradictory reason, / If there is no sublation.'"
