Mbh 12.220.2a

"'Bhishma said, "The ancients who had their understandings directed to the Srutis, highly applauded the duty of self-restraint for all the orders generally but for the Brahmanas in especial. Success in respect of religious rites never occurs in the case of one that is not self-restrained. Religious rites, penances, truth,--all these are established upon self-restraint. Self-restraint enhances one's energy. Self-restraint is said to be sacred. The man of self-restraint becomes sinless and fearless and wins great results. One that is self-restrained sleeps happily and wakes happily. He sojourns happily in the world and his mind always remains cheerful. Every kind of excitement is quietly controlled by self-restraint. One that is not self-restrained fails in a similar endeavour. The man of self-restraint beholds his innumerable foes (in the form of lust, desire, and wrath, etc.), as if these dwell in a separate body. Like tigers and other carnivorous beasts, persons destitute of self-restraint always inspire all creatures with dread. For controlling these men, the Self-born (Brahman) created kings. In all the (four) modes of life, the practice of self-restraint is distinguished above all other virtues. The fruits of self-restraint are much greater than those obtainable in all the modes of life. I shall now mention to thee the indications of those persons who prize self-restraint highly.[829] They are nobility, calmness of disposition, contentment, faith, forgiveness, invariable simplicity, the absence of garrulity, humility, reverence for superiors, benevolence, compassion for all creatures, frankness, abstention from talk upon kings and men in authority, from all false and useless discourses, and from applause and censure of others. The self-restrained man becomes desirous of emancipation and, quietly bearing present joys and griefs, is never exhilarated or depressed by prospective ones.
