These six should be renounced like a splitting vessel in the sea, viz., a preceptor that cannot expound the scriptures, a priest that is illiterate, a king that is unable to protect, a wife that speaketh disagreeable words, a cow-herd that doth not wish to go to the fields, and a barber that wisheth to renounce a village for the woods. Verily, those six qualities should never be forsaken by men, viz., truth, charity, diligence, benevolence, forgiveness and patience. These six are instantly destroyed, if neglected, viz., kine, service, agriculture, a wife, learning, and the wealth of a Sudra. These six forget those who have bestowed obligations on them, viz., educated disciples, their preceptors; married persons, their mothers; persons whose desires have been gratified, women; they who have achieved success, they who had rendered aid; they who have crossed a river, the boat (that carried them over); and patients that have been cured, their physicians. Health, unindebtedness, living at home, companionship with good men, certainty as regards the means of livelihood, and living without fear, these six. O king, conduce to the happiness of men. These six are always miserable, viz., the envious, the malicious, the discontented, the irascible, the ever-suspicious, and those depending upon the fortunes of others.
