gṛhe gurāv araṇye vā nivasann ātmavān dvijaḥ / nāvedavihitāṃ hiṃsām āpady api samācaret //
A twice-born man of virtuous disposition, whether he dwells in (his own) house, with a teacher, or in the forest, must never, even in times of distress, cause an injury (to any creature) which is not sanctioned by the Veda.
