Yonassan Gershom (born 1947) is an American Rabbi and writer who was ordained in the Jewish Renewal movement during the 1980s, and is now a follower of Breslov Hasidism.

[3] In 1997, he made a pilgrimage to the grave of Rabbi Nachman of Breslov in Uman, Ukraine, a trip that has strongly influenced his later writings.

Thus, he argues, it is possible that the Nazis committed the Holocaust due to the evil they had accumulated through many lifetimes of persecuting and killing Jews throughout the preceding centuries.

The Duluth, Minnesota, PBS station, WDSE, also featured him on their Venture North news magazine show, in connection with his philosophy on gardening and Jewish spirituality.

Although he is best known for his books on reincarnation, Gershom is also a life-long pacifist and peace activist, who has written many articles on Judaism and non-violence, later collected into an anthology entitled, Eight Candles of Consciousness.
