佛遺教經論疏節要 1.56

1.56

節身者，儉絕他求，勤捨放逸。時食者，離非時食，於食知止足也。清淨自活者，不相追求，遠離四邪故。不預世事者，自性止多事故。不通使命者，自性不作輕賤事故。夫出家者，無為無欲孤高自守，若為使命則降志辱身、癈亂正業。《易》曰「不事王侯，高尚其事。」況乎形服超世而甘為賤役，良用慨然。律開為父母等馳書往返，一切不犯。

"Restrain the body": be frugal and sever other pursuits, diligently abandoning laxity. "Eat at proper times": depart from eating at improper times, knowing contentment with food. "Live purely by oneself": do not pursue one another, keeping far away from the four improper livelihoods. "Do not participate in mundane affairs": by nature ceasing troublesome affairs. "Do not carry messages and missions": by nature not performing menial matters. Indeed, one who has left home is free from contrivance and desire, aloof and self-controlled; if one acts as an envoy on missions, one lowers one's resolve and humiliates one's body, disrupting and confusing one's correct vocation. The Yijing says: "Not serving kings and princes, keeping one's endeavor noble." How much more so when one's appearance and dress transcend the world, yet one willingly engages in menial servitude—this truly arouses deep lamentation! The Vinaya permits carrying letters back and forth for one's parents and the like, none of which is a violation.
