If he by chance does anything mean, he should never deny it, but if he has done it, he should say: 'I have done it;' if he has not done it, 'I have not done it.' (11)
He should not, in every case, wait for the express command (of the teacher) like an unbroken horse for the whip (of the rider), but like a broken horse which sees the whip (of the rider) he should commit no evil act. (12)
Disobedient, rough speaking, ill-behaved pupils will exasperate even a gentle teacher; but those will soon win even a hot-tempered teacher who humour him and are polite. (13)
He should not speak unasked, and asked he should not tell a lie; he should not give way to his anger, and bear with indifference pleasant and unpleasant occurrences. (14)
Subdue your Self, for the Self is difficult to subdue; if your Self is subdued, you will be happy in this world and in the next. (15)
Better it is that I should subdue my Self by self-control and penance, than be subdued by others with fetters and corporal punishment. (16)
He should never do anything disagreeable to the wise, neither in words nor deeds, neither openly nor secretly. (17)
He should not (sit) by the side of the teacher, nor before him, nor behind him; he should not touch (the teacher's) thigh with his own, nor answer his call from the couch. (18)
A well-behaved monk should not sit on his hams, nor cross his arms, nor stretch out his legs, nor stand (too) close to his teacher. (19)
