又正法念經云。孔雀菩薩為諸天眾說調伏法。若在家出家。若老若少。調伏相應。以此莊嚴。如出家之人初以袈裟而自調伏。當行七事。一者如其國法受糞掃衣。在家之人所棄之衣。若在塚間有死人衣。死屍所壓則不應取。若於塚間得破壞衣則應受用。是名袈裟調伏之法。

Furthermore, the Saddharmasmṛtyupasthāna-sūtra says: The Peacock Bodhisattva explained the method of subduing the mind (damana) to the assembly of devas: "Whether householder or renunciant, whether old or young, if one's subjugation is appropriate, one is adorned by this. As a renunciant initially subdues himself by means of the kāṣāya robe, he should practice seven matters: First, in accordance with the law of that land, he accepts rag robes—garments discarded by householders. If in a cemetery there are garments of the dead, those pressed beneath a corpse should not be taken; if in a cemetery one obtains tattered garments, one should accept and use them. This is called the method of subverting defilements through the kāṣāya robe.
