Reb Nachman of Breslov, also known as Reb Nachman of Bratslav, Reb Nachman Breslover, Rabbi Nachman from Uman (April 4, 1772 – October 16, 1810), was the founder of the Breslov Hasidic dynasty.
Rebbe Nachman, a great grandson of the Baal Shem Tov, breathed new life into the Hasidic movement by combining Kabbalah with in-depth Torah scholarship. He attracted thousands of followers during his lifetime and his influence continues until today. Rebbe Nachman's religious philosophy revolved around closeness to Hashem and speaking to Hashem in normal conversation as you would with a best friend. The concept of hitbodedut is central to his thinking.
His published work includes Likutey Moharan / ליקוטי מהר"ן (Chassidic interpretations of the Tanach, Midrashim, etc.), Tikkun HaKlali / תיקון הכללי (Rebbe Nachman's order of ten Psalms to be recited for various problems, plus commentary by Reb Noson. Published as a separate book in 1821), and Sippurei Maasiyos / סיפורי מעשיות (Thirteen seemingly simple tales in Hebrew and Yiddish that are filled with deep mystical secrets. The longest of these tales is The Seven Beggars (read the full story), which contains many Kabbalistic themes and hidden allusions. Several fragmentary stories are also included in Rabbi Aryeh Kaplan's translation of the complete tales, Rabbi Nachman's Stories).
