Mbh 10.5.1

"'Kripa said, "A person who is bereft of intelligence and who hath not his passions under control, cannot, even if he waits dutifully upon his superiors, understand all the considerations of morality. This is my opinion. Similarly, an intelligent person who does not practise humility fails to understand the settled conclusions of morality. A brave man, if bereft of understanding, by waiting all his life upon a learned person fails to know his duties, like a wooden ladle unable to taste the juicy soup (in which it may lie immersed). The wise man, however, by waiting upon a learned person for even a moment, succeeds in knowing his duties, like the tongue tasting the juicy soup (as soon as it comes into contact with the latter). That person who is endued with intelligence, who waits upon his superiors, and who has his passions under control succeeds in knowing all the rules of morality and never disputes with what is accepted by all. An ungovernable, irreverent, and sinful person of wicked soul perpetrates sin in seeking his well-being by disregarding destiny.
