Mahabharata Udyoga Parva Chapter 34:2

Mahabharata Udyoga Parva Chapter 34:2 Great prosperity waiteth upon him who hath subdued his senses, or controlled his soul, or who is capable of punishing all offenders, or who acteth with judgment or who is blessed with patience. One's body, O king, is one's car; the soul within is the driver; and the senses are its steeds. Drawn by those excellent steeds, when well-trained, he that is wise, pleasantly performeth the journey of life, and awake in peace. The horses that are unbroken and incapable of being controlled, always lead an unskilful driver to destruction in the course of the journey; so one's senses, unsubdued, lead only to destruction. The inexperienced wight, who, led by this unsubdued senses, hopeth to extract evil from good and good from evil, necessarily confoundeth misery with happiness. He, who, forsaking religion and profit, followeth the lead of his senses, loseth without delay prosperity, life, wealth and wife. 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. Self-knowledge and steadiness, patience and devotion to virtue, competence to keep counsels and charity,—these, O Bharata, never exist in inferior men. Fools seek to injure the wise by false reproaches and evil speeches. The consequence is, that by this they take upon themselves the sins of the wise, while the latter, freed from their sins, are forgiven. In malice lieth the strength of the wicked; in criminal code, the strength of kings, in attentions of the weak and of women; and in forgiveness that of the virtuous. To control speech, O king, is said to be most difficult.
