成唯識論述記 6.136

6.136

述曰：起欲等五，或俱、不俱。所以知者，《瑜伽》第三說四一切，說此五種無後二故。第三是時，第四是俱，未必俱故。若言，欲等行相不俱增，故彼不說俱。五體既俱有，彼處應說。

The Commentary states: The arising of the five, desire and so forth, may be concurrent or not concurrent. How this is known: fascicle three of the *Yogācārabhūmi* speaks of the four universals, and states that these five kinds lack the latter two [universals]. The third is time, and the fourth is concurrence; because they are not necessarily concurrent. If one says that their mental modes do not increase concurrently and therefore that text does not say they are concurrent, since the substances of the five would both be present, it should have spoken of it there.
