剃除须发，而为沙门。
受道法者，去世资财，乞求取足。
日中一食，树下一宿，慎勿再矣。
使人愚蔽者，爱与欲也。
— 释迦牟尼佛
《四十二章经》: 第三章
Shaving to rid beard and hair, then as Śramaṇas. Those receiving the path’s Dharma, eradicate worldly goods and wealth, with begging to obtain what suffices. At midday with one meal, at trees below for one night, cautious to not again do so. That which enable people to be foolish and dull, are attachments and desires.
— Śākyamuni Buddha
