The Commentary states: In the third [interpretation], Sthiramati (Ānhui) asserts that the previous one is not correct. Because the phrase 'the two are each twofold' occurs only after the four indeterminate factors, it is not explaining the preceding defiled dharmas. One should say that the first 'two' indicates two kinds of 'two': first, the two of remorse and sleep; second, the two of investigation and evaluation. How is this known? In Sanskrit, dvayam and dvaye are distinct. Dvayam merely means 'two': within a single noun it denotes one kind of 'two', referring generally to two, which is just one single pair. Now the Sanskrit text reads dvaye, which within a dual noun denotes the meaning of two kinds of 'two'. Therefore, a single expression of 'two' reveals two kinds of 'two', differing from the earlier dvayam. If it were not so, what other reason would there be? A single word 'two' denotes two kinds of 'two' because the declensions (vibhakti) are distinct.
