「云何思擇？一行」者，《對法》第十五云：謂以一法與餘法一一互相問，除此法，更以第二法與餘法互相問，如是一一，一切當知。　「順前句」者，謂諸法中隨取二法更互相問，依止前法，以答所問，以狹問寬，順前句故。　「順後句」者，謂即二法展轉相問，依止後問，以答所問，以寬問狹，順後句故。一切狹體必即寬故，自有寬體非是狹故。或於所問，應二句答，應三句答，應四句答，此中從寬以明，唯說四句。體有覺狹，或不同故，寬狹義同，應述可答。不如理名無事答，亦名遮止答。其二十八對二門、五對三門等，皆如〈決擇分〉六十五、六、七、八等說。　「四行迹法」，謂苦速通等。二文不同，至下當釋。

Regarding "How does one examine? One activity […]", the fifteenth fascicle of the Abhidharmasamuccaya-bhāṣya says: it means taking one dharma and questioning each of the other dharmas reciprocally; setting aside this dharma, one further takes a second dharma and questions the other dharmas reciprocally; in this way, one should know all of them one by one. / "Conforming to the preceding phrase" means taking any two dharmas among the various dharmas and questioning them reciprocally, relying on the preceding dharma to answer what was asked; asking about the broader by means of the narrower conforms to the preceding phrase. / "Conforming to the subsequent phrase" means taking those two dharmas and questioning them back and forth, relying on the subsequent question to answer what was asked; asking about the narrower by means of the broader conforms to the subsequent phrase. Because every narrower entity must necessarily be the broader, while there are broad entities that are not the narrow. Alternatively, regarding what is questioned, one should answer with two phrases, three phrases, or four phrases; here, explaining in accordance with the broader, it speaks only of four phrases. Because entities have distinctions of narrower and broader, or because they are not identical, when the narrower and broader meanings are identical, one should answer by affirmation. What is improper is called answering without fact, and is also called answering by negation. The twenty-eight pairs of twofold gates, five pairs of threefold gates, etc., are all as explained in fascicles 65, 66, 67, 68, etc., of the Viniścayasaṃgrahaṇī. / "The four modes of practice" refers to painful with swift direct knowledge, etc. The two texts differ, and will be explained below.
