Rabbi Yisroel Dov Ber Odesser () (approx. 1888 – 23 October 1994), also known as Reb Odesser or Sabba ("grandfather" in Hebrew), was a Breslover Hasid and rabbi who claimed to have received a Letter From Heaven sent directly to him by Rebbe Nachman of Breslov, who had died 112 years earlier, revealing to him a new remedy for relieving the world's suffering and illness. This remedy is the song and name Na Nach Nachma Nachman Meuman, which he revealed in his old age to newfound followers throughout Israel; when he was younger he sent it to the chasidim before the shoa, including Rabbi Itshak Briter in Poland to their request, but since the war begun they had to send it back so it wouldn't be destroyed. His following developed into the Na Nach movement. Introduction to Breslov Odesser was born in Tiberias when Israel were under Ottoman rule, to a family which for generations were Karliner Hasidim. (His great-great-grandfather, Rabbi Yekutiel Zalman Leib, was a close disciple of Rabbi Abraham Kalisker, a major disciple of the Baal Shem Tov.) In his youth, Odesser also followed the Karliner way, but felt it was not fulfilling his soul. Odesser first came into contact with the teachings of Rebbe Nachman of Breslov as a young yeshiva student in Tiberias. Someone had ripped the cover off a Hebrew language holy book and thrown it into the garbage. Orthodox Judaism forbids defacing a holy book in this way, so Odesser rescued it with the intention of burying it, as is proper for worn-out Jewish holy books. Before discarding it, however, he decided to read it. This book was Hishtafchut HaNefesh (Outpouring of the Soul) by Alter Tepliker, which contains excerpts from Rebbe Nachman's writings about meditation and personal prayer. Because the cover was missing, Odesser did not know who the author was, but the teachings worked for him. Only later did he learn it was a Breslover book. The first Breslover Hasid whom he met in person was Rabbi Yisroel Halpern (also known as Yisroel Karduner), who came one day to buy bread from Odesser's parents. The young Odesser knew immediately that he had found his teacher, but his parents were strongly opposed to the Breslover path. Eventually his father threw him out of the house and attempted to stop his upcoming wedding. This did not deter him, and he continued to study with
