Therefore must we strive to do what is virtuous and forbear from doing what is unrighteous. Whoever with a heart full of gratefulness and free from malice strives to do what is good, attains wealth, virtue, happiness and heaven (hereafter). Those who are purified of sins, wise, forbearing, constant in righteousness, and self-restrained enjoy continuous felicity in this as well as in the next world. Man must follow the standard of virtue of the good and in his acts imitate the example of the righteous. There are virtuous men, versed in holy writ and learned in all departments of knowledge. Man's proper duty consists in following his own proper avocation, and this being the case these latter do not become confused and mixed up. The wise man delights in virtue and lives by righteousness. And, O good Brahmana, such a man with the wealth of righteousness which he hereby acquires, waters the root of the plant in which he finds most virtue. The virtuous man acts thus and his mind is calmed. He is pleased with his friends in this world and he also attains happiness hereafter. Virtuous people, O good man, acquire dominion over all and the pleasure of beauty, flavour, sound and touch according to their desire. These are known to be the rewards of virtue. But the man of enlightened vision, O great Brahmana, is not satisfied with reaping the fruits of righteousness.
