The long Baal Shem Tov story, part 5

Back in Prague, R. Yehudah Aryeh slowly forgets about his brother R. Moshe's sorry state. He sends his grandsons to learn with the Tosfos YomTov, and one of them, Avraham Moshe, receives special instruction in Kabbalah. Soon, an old friend of the family reminds them that their ancestor R. Shmuel Tzadok was punished with a son like R. Moshe because he himself would ridicule those who studied kabbalah. Avraham Moshe is saddened to hear of his great-uncle Moshe's situation, and asks R. Eliyahu Baal Shem, recently moved to Prague for advice.
