A victory gained by an untruth, deceitful conduct towards the king, and insincerity of intentions expressed before the preceptor,—these three are each equal to the sin of slaying a Brahmana. Excessive envy, death, and boastfulness, are the causes of the destruction of prosperity. Carelessness in waiting upon a preceptor, haste, and boastlessness, are the three enemies of knowledge.

In plain words: Winning by lying, cheating the king, and being fake with your teacher are each as bad as the worst sin, killing a Brahmana (a priest). Too much envy, pride, and boasting destroy good fortune. Not respecting your teacher, rushing, and boasting are the three enemies of learning.
