Musar for Sukkah 103:13

The prophet Jeremiah 9,22, says concerning these three attributes: "Let not the wise boast of his wisdom, nor the hero of his valour, nor the rich of his wealth." What the prophet means is that if these virtues are merely physical attributes, they are nothing but being vainglorious, greedy and jealous, i.e. קנאה, תאוה, כבוד. However, כי עם בזאת יתהלל המתהלל, "but if these three attributes are spiritual in nature, then such a person may boast of his close relationship with Me."
