Spiritual Tools: Rav Aharon Karliner: Mikvah

The 17th of Sivan is the Yahrtzeit of Rav Aharon ben Asher of Karlin, the author of Beit Aharon: I heard that the Baal Shem Tov, his mempry for a blessing, had said that he would say Psalms while in the Mikvah (Mazkeret Shem haGedolim, page 139)

Immerse no fewer than two times: Once to remove uncleanness and once to draw holiness on yourself (Hanhagot Tzaddikim, Page 3, #3). [Rabbi Yitzhak Buxbaum, Jewish Spiritual Practices, pages 566-7]
