Vidura said: 'Honored for his virtue and free from pride, the good man who pursues his purpose without exceeding his own power soon succeeds in winning fame, for the virtuous, once pleased with a man, are surely able to grant him happiness. He who of his own accord forsakes even a great purpose because it harbors unrighteousness lives happily, casting off all his sorrows as a snake casts off its worn-out skin. Victory won through falsehood, deceitful conduct toward the king, and insincerity of purpose expressed before one's teacher — these three are equal to the sin of killing a brahmin. Excessive envy, death, and boastfulness are causes that ruin prosperity; negligence in attending upon one's teacher, haste, and self-praise are the three enemies of knowledge. Intellect, restlessness, idle pastimes to pass the time, arrogance, pride, and greed — these seven, it is said, are the faults that beset students in their pursuit of learning. How can those who desire pleasures possess knowledge?'
