成唯識論述記 7.117

7.117

述曰：自下第六、與善俱門。初、二唯與十善容俱，欲界無輕安故。前第六卷善中，雖有異解，欲有輕安，無是正文，故今據後說。設許亦有亦無輕安，非定引生故。尋、伺十一俱，增輕安故。有人云：三藏言：西方有二說：一云未至定有尋、伺，非根本地者，不然，尋、伺支非未至故，論有誠文說初靜慮也。

The Commentary states: From here down is the sixth section: being accompanied by wholesome factors. The first two can only be accompanied by ten wholesome factors, because the desire realm lacks pliancy (praśrabdhi). Although there was a different interpretation under the wholesome factors in the preceding sixth fascicle that the desire realm possesses pliancy, there is no definitive canonical text for it; hence it is now based on the latter statement. Even if one grants that pliancy exists or does not exist, it is not definitely induced. Vitarka and vicāra accompany eleven, with the addition of pliancy. Someone says: The Tripiṭaka Master stated that there are two views in the Western regions: one says that the threshold dhyāna (anāgamya-samādhi) has vitarka and vicāra, not the fundamental bhūmi. This is not correct, because the factors of vitarka and vicāra do not belong to the threshold; there is explicit text in treatises stating that they belong to the first dhyāna.
