Good Deeds and Wisdom

Rabbi Chanina ben Dosa used to say: “Anyone whose good deeds exceed his wisdom, his wisdom will endure; but anyone whose wisdom exceeds his good deeds, his wisdom will not endure... “(Ethics 3:10)

Through study a person learns how to do a mitzva (commandment). Nevertheless, the final deed is the main thing, for the deed causes an additional measure of spiritual light to infuse the level of wisdom. In this way, a person’s wisdom will not merely survive, but also endure. (Sefer HaMa’amarim 5654)
