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。此有三處可修禪定：一者、深山絕人之處；二者、頭陀蘭若之處，離於聚落極近二里，此放牧聲絕，無諸憒鬧；三者、遠白衣舍處，清淨伽藍之中，皆是閑居靜處也。

Third, obtaining a quiet and secluded dwelling: "Quiet" means not engaging in myriad affairs, hence called quiet. Being free from bustle and clamor, it is called "secluded." There are three places where one can cultivate dhyāna-concentration: First, deep mountains, places cut off from human beings. Second, an araṇya for dhūta practice, separated from villages by at least two li, where the sounds of herding cattle cease and there is no bustle or clamor. Third, far from the dwellings of white-robed laity, within a pure saṅghārāma. These are all quiet and secluded dwellings.
