瑜伽師地論略纂 8.31

8.31

論解「思惟起想，巧便而臥」中云「如林野鹿」者，野鹿恐人傷殺，眠不安隱，有巧便宿人，當今臥時亦爾。

Where the treatise explains "reflecting on the notion of rising, lying down with skillful means," saying, "Like a wild deer in the forest": A wild deer fears being harmed and killed by people, so its sleep is not peaceful; a person who has skillful means for resting is also like this when currently lying down.
