瑜伽師地論略纂 8.30

8.30

論「又為護持諸臥具故，順世威儀」等者，此中意，於初夜分由盡經行故，後夜分不令經行。初夜經行不令遠去，或至書經行處，恐賊盜失臥具，所以進臥具，令經行。又雖是夜中，威儀須正，故順世儀，初夜經行。又世俗初夜經行，合僧初夜經行，此順世儀故同。初夜經行，有二因緣：一、護持臥具，所以不遠；順世儀故，書分經行。

Where the treatise says, "Furthermore, in order to guard bedding and seating, and to accord with worldly deportment," and so forth: The meaning here is that during the early watch of the night, because one fully engages in walking meditation, one is not made to engage in walking meditation during the later watch of the night. During the early watch, walking meditation is not allowed to go far, or goes to the daytime walking area; fearing that thieves might steal the bedding and seating, one is made to walk near the bedding and seating. Furthermore, although it is during the night, deportment must be proper; thus, according with worldly deportment, one does walking meditation in the early watch of the night. Moreover, in worldly custom there is walking meditation in the early watch of the night, and the gathered saṃgha performs walking meditation in the early watch of the night; this accords with worldly deportment and is thus identical. There are two conditions for walking meditation in the early watch of the night: first, guarding the bedding and seating, which is why one does not go far; second, according with worldly deportment, so one walks during the daytime period.
