修習止觀坐禪法要 1.19

1.19

第三、得閑居靜處。閑者，不作眾事，名之為閑。無憒鬧故，名之為靜。有三處可修禪定：一者、深山絕人之處。二者、頭陀蘭若之處；離于聚落極近三四里，此則放牧聲絕，無諸憒鬧。三者、遠白衣住處，清淨伽藍中。皆名閑居靜處。

Third, obtaining an unoccupied and quiet place. "Unoccupied" means not engaging in manifold tasks; "quiet" means being free from clamor. There are three places where one can cultivate dhyāna-concentration: First, deep in the mountains, in places secluded from people. Second, in a dhūta araṇya, at least three to four li away from settlements, where the sounds of pasturing cattle have ceased and there is no clamor. Third, in a pure monastery far removed from lay residences. All these are called unoccupied and quiet places.
