成唯識論演祕 5.297

問：何故《瑜伽》五十六云：「謂輕安俱三摩地及彼眷屬，并彼果法所不攝義，是欲界繫。」既云輕安所不攝故，方名欲界，云何言欲得有輕安？

Question: Why does Yogācārabhūmi, fascicle 56, say: "It means that the meaning of not being subsumed by samādhi concomitant with pliancy, its retinue, and its resultant phenomena, is tied to the desire realm"? Since it says that only because it is not subsumed by pliancy is it called the desire realm, how can one say that the desire [realm] can have pliancy?
