He that is not envious and is possessed of wisdom, by always doing what is good, never meeteth with great misery; on the other hand, he shineth everywhere. He that draweth wisdom from them that are wise is really learned and wise. And he that is wise, by attending to both virtue and profit, succeedeth in attaining to happiness. Do that during the day which may enable thee to pass the night in happiness; and do that during eight months of the year which may enable thee to pass the season of rains happily.

In plain words: A wise person who isn't jealous and always does good never suffers greatly and is admired everywhere. Truly learned people learn from the wise. Vidura says to plan ahead: do things in the day so you can rest happily at night, and work during the good months so you are ready for the rainy season.
