A Jewish Buddhist (also Jubu or Buju) is a person with a Jewish ethnic or religious background who practices forms of Buddhist meditation and spirituality. The term Jubu was first brought into wide circulation with the publication of The Jew in the Lotus by Rodger Kamenetz. In some cases, the term can refer to individuals who practice both traditions, in other cases "Jewish" is no more than an ethnic designation, where the person's main religious practice is Buddhism. In yet other cases, a Jubu is simply a Jew with an interest in Buddhism. A large demographic of Jewish Buddhists, constituting its majority, still maintain religious practices and beliefs in Judaism coupled with Buddhist practices and perhaps beliefs.
