Haazinu Shabbos Shuvah

Haazinu Shabbos Shuvah: "troubled him greatly. One night, in a dream, he saw that they were lifting him up to the supernal worlds, taking him into ever more recondite chambers, until he could no longer see due to the great supernal illumination, and had to shut his eyes. Finally, they brought him to one inner chamber and said to him, 'Open your eyes.' He opened them and beheld many great sages and Tzaddikim sitting and studying Torah, with the Baal Shem Tov sitting at the head of them all. The Baal Shem Tov said to him, 'Why are you having so much trouble understanding the Tosephos. The answer is as follows..' When the scholar awoke in the morning, he took his Gemara and looked over the words of the Tosephos. He saw that the Baal Shem Tov's answer was remarkably clear. Nevertheless, he still thought that it was only a dream. When the holy Shabbos arrived, he went to the Third Meal2 of the Baal Shem Tov. As soon as he walked into the house, the Baal Shem Tov said to him, 'Welcome! Did you look over explanation of the Tosephos that I told you to see if it is true?' From that day on, he attended to the Baal Shem Tov and became a great Chasid. I heard this from honest individuals. Kesser Shem Tov 2, p. 16a"
