1.442

(The Buddha said: "One should have the one who has received the upasampadā go ahead in front." The disciple must inquire after the upādhyāya at the three times of the day: morning, noon, and evening. He must perform two tasks for the upādhyāya, and despite toil and hardship he must not make excuses: first, repairing the rooms; second, mending and washing robes. If the upādhyāya instructs entirely in accordance with the Dharma, he must carry it all out; if he disobeys, he is to be dealt with in accordance with the Dharma.)
