Vidura said: "O foremost of kings, son of Vicitravirya, Manu Svayambhuva spoke of these seventeen kinds of men as being like one who strikes the empty sky with his fists, or strives to bend the unbendable bow of Indra in the heavens, or longs to seize the intangible rays of the sun. These seventeen kinds of fools are: he who strives to govern one who cannot be governed; he who instructs an unworthy disciple; he who grows angry without cause; he who turns for too long to one who hates him; he who fails to protect his women -- may good come to him nonetheless; he who begs from one who should never be begged; he who boasts when asked for something; he who, though nobly born, commits an improper act; he who, being weak, wages ceaseless war against the strong; he who speaks earnestly to one who has no faith in him; he who desires what should never be desired, O lord of men; a father-in-law who jests with his daughter-in-law, or who, dwelling under the same roof, seeks her esteem; he who sows his seed in another man's field; and he who reviles his own wife beyond all measure -- these seventeen fools did Manu describe."
