चोदितो गुरुणा नित्यमप्रचोदित एव वा । कुर्यादध्ययने यत्नमाचार्यस्य हितेषु च ॥ १९१ ॥
Both when ordered by his teacher, and without a (special) command, (a student) shall always exert himself in studying (the Veda), and in doing what is serviceable to his teacher.
Let him always keep his right arm uncovered, behave decently and keep his body well covered, and when he is addressed (with the words), ’Be seated,’he shall sit down, facing his teacher.
In the presence of his teacher let him always eat less, wear a less valuable dress and ornaments (than the former), and let him rise earlier (from his bed), and go to rest later.
