Mbh 3.206.4c

Those who are not swayed by anger, pride, haughtiness and envy, and those who are quiet and straight-forward, are men of virtuous conduct. Those who are diligent in performing the rites enjoined in the three Vedas, who are wise, and of pure and virtuous conduct, who exercise self-restraint and are full of attention to their superior, are men of virtuous conduct. The actions and conduct of such men of great power, are very difficult of attainment. They are sanctified by the purification of their own actions, and consequently sin in them dies out of itself. This virtue of good conduct is wonderful, ancient, immutable and eternal; and wise men observing this virtue with holiness, attain to heaven. These men who believe in the existence of the Deity, who are free from false pride, and versed in holy writ, and who respect regenerate (twice-born) men, go to heaven. Among holy men, virtue is differentiated in three ways--that great virtue which is inculcated in the Vedas, the other which is inculcated in the dharmashastras (the minor scriptures), and virtuous conduct. And virtuous conduct is indicated by acquisition of knowledge, pilgrimage to sacred places, truthfulness, forbearance, purity and straight-forwardness. Virtuous men are always kind to all creatures, and well-disposed towards regenerate men. They abstain from doing injury to any creature, and are never rude in speech. Those good men who know well the consequences of the fruition of their good and evil deeds, are commended by virtuous men. Those who are just and good-natured, and endowed with virtue, who wish well of all creatures, who are steadfast in the path of virtue, and have conquered heaven, who are charitable, unselfish and of unblemished character, who succour the afflicted, and are learned and respected by all, who practise austerities, and are kind to all creatures, are commended as such by the virtuous.
