2.98

人事沙門道人當用五事：一以善心向之；二擇好言與語；三以身敬之；四當慈慕之；五沙門道人，人中雄師，當敬事之。

For a person serving a śramaṇa or a man of the Way, there are five things that should be applied: first, direct a wholesome mind toward him; second, select fine words to speak to him; third, revere him with one's body; fourth, cherish and admire him with kindness; fifth, [recognise that] the śramaṇa or man of the Way is a lion among men, and respectfully serve him.
