Mbh 11.7.2b

He who followeth after those running steeds has to come repeatedly to this world in a round of rebirths. He, however, who, being self-restrained restrains them by his understanding hath not to come back. They, however, that are not stupefied while wandering in this wheel of life that is revolving like a real wheel, do not in reality wander in a round of rebirths. He that is wise should certainly take care to prevent the obligation of rebirth. One should not be indifferent to this, for indifference may subject us to it repeatedly. The man, O king, who has restrained his senses and subdued wrath and covetousness, who is contented, and truthful in speech, succeeds in obtaining peace. This body is called the car of Yama. Then those that are of little intelligence are stupefied by it. Such a person, O king, would obtain that which thou hast obtained. The loss of kingdom, of friends, and of children, O Bharata, and such as these, overtake him who is still under the influence of desire. He that is wise should apply the medicine of intelligence to all great griefs. Indeed, obtaining the medicine of wisdom, which is truly very efficacious and is almost unattainable, the man of restrained soul would kill that serious disease called sorrow. Neither prowess, nor wealth, nor friends, nor well-wishers can cure a man of his grief so effectually as the self-restrained soul. Therefore, observant of the great duty of abstention from all injuries, or friendship for all creatures, be of pious behaviour, O Bharata! Self-restraint, renunciation, and heedfulness are the three steeds of Brahman. He who rides on the car of his soul, unto which are yoked these steeds with the aid of traces furnished by good conduct, and drives it, casting off all fear of death, proceedeth, O king, to the regions of Brahman. That person, O monarch, who gives unto all creatures an assurance of his harmlessness, goes to the highest of regions, the blessed realm of Vishnu.
