SimchaMinute by Rabbi Avigdor Miller
Hashem gave Mordechai a gift of wisdom. He became the greatest scholar in the Jewish nation, the head of the Sanhedrin. What else did he get? The gift of understanding!
Understanding [daas] is a different story entirely. A man can have a lot of knowledge but lack daas. It is not enough to be a living Talmud; we must understand what it means... It should not be mere intellectual teachings. But, it has to become part of us. — Preface to Purim 2 (#112)
