二十九。（佛在舍衛，蘭若比丘為賊打奪什物，佛令留寄村舍；六群寄衣遊行，因制。）名中。有難簡非安靜，蘭若標異前戒。此謂空野比丘慮賊奪衣，佛開寄於村聚，身在蘭若，無慮奪失故也。

Twenty-nine. (The Buddha was in Śrāvastī; an araṇya bhikṣu was robbed of his belongings by bandits, so the Buddha ordered them to be left deposited in village houses; the group-of-six deposited their robes and went wandering, hence the prohibition was enacted.) In the name: having peril clarifies that it is not tranquil; araṇya marks the distinction from the previous precept. This means that when a wilderness bhikṣu fears bandits will seize his robes, the Buddha permits depositing them in villages or settlements, so that with his person in the araṇya, he has no fear of robbery or loss.
