四分律行事鈔資持記 3.78

3.78

四中。幽顯俱訶者，乖威儀故。《涅槃》亦云：衣服不淨，法滅之相。今時有人故著弊衣，妄稱道者；內無慚恥，外失威儀；污辱吾門，何道之有！

In the fourth [part], 'Both the unseen and seen worlds rebuke' because it contradicts deportment. The *Nirvāṇa Sūtra* also says: 'Impure robes are a sign of the Dharma's destruction.' Nowadays, there are people who deliberately wear ragged robes and falsely call themselves practitioners of the Way; internally they have no shame or conscience, and externally they lose deportment. They defile and disgrace our lineage—what Way is there in them!
