He, who is the master of riches but not of his senses, certainly loseth his riches in consequence of his want of mastery over his senses. One should seek to know one's self by means of one's own self, controlling one's mind, intellect, and senses, for one's self is one's friend as, indeed, it is one's own foe. That man, who hath conquered self by means of self, hath his self for a friend, for one's self is ever one's friend or foe. Desire and anger, O king, break through wisdom, just as a large fish breaks through a net of thin cords. He, who in this world regarding both religion and profit, seeketh to acquire the means of success, winneth happiness, possessing all he had sought. He, who, without subduing his five inner foes of mental origin, wisheth to vanquish other adversaries, is, in fact, overpowered by the latter. It is seen that many evil-minded kings, owing to want of mastery over their senses, are ruined by acts of their own, occasioned by the lust of territory. As fuel that is wet burneth with that which is dry, so a sinless man is punished equally with the sinful in consequence of constant association with the latter. Therefore, friendship with the sinful should be avoided. He that, from ignorance, faileth to control his five greedy foes, having five distinct objects, is overwhelmed by calamities. Guilelessness and simplicity, purity and contentment, sweetness of speech and self-restraint, truth and steadiness,--these are never the attributes of the wicked.
