四分律行事鈔資持記 1.1105

1.1105

《四分》亦三，初明客來不移。同上可見。若分下，簡非處。若有下，明預定。律因諸比丘見阿練若好窟，念言當於此安居；後餘比丘見已，亦如是作念；至十六日共至，住處迮狹，佛聽先作相者住；即書云某甲欲於此安居。詳此，似非分房；應是山間嵓窟庵舍孤立之處，可自標定；必是僧坊，自行分法，理無預占。滅名去者，恐妨後人故。滅即除也。

The Dharmaguptaka-vinaya also has three [sections]: first, it clarifies that when guests arrive, one does not move. This is the same as above and is evident. Under 'if dividing...', it excludes improper places. Under 'if there are...', it clarifies advance reservation. The Vinaya's nidāna tells that several bhikṣus saw a fine cave in an araṇya and thought, 'We should enter the rains retreat here.' Later, other bhikṣus saw it and also formed this thought. When the sixteenth day arrived they came together, but the dwelling place was cramped; the Buddha permitted whoever made a mark first to dwell there, namely writing: 'So-and-so wishes to enter the rains retreat here.' Examining this closely, it does not seem to be the division of rooms; it must be an isolated mountain cliff cave or hut, where one may mark and reserve it on one's own. If it is a monastery, the procedure of division is naturally practiced, and in principle there is no advance occupation. Removing the name when leaving is done out of concern for obstructing later people. 'Erasing' means removing.
