The Baal Shem Tov, or Besht —  the founder of Chasidism — 
met the soul of the Messiah during an ascent to heaven. 
The Besht asked him, "When will the Master come?" 
The Messiah answered, "When your wellsprings break forth to the outside!" 
(from a letter written by the Besht to his brother-in-law about one of his soul ascents) 


Rabbi David's teaching

Click here for selected events and publications. Click here for a brochure describing Rabbi Seidenberg's teaching and scholar-in-residence work.

Rabbi David Seidenberg, the creator of NeoHasid, teaches text and music, dance, and ecology, and all aspects of Jewish thought and spirituality, in their own right and in relation to ecology and the environment. Areas include Kabbalah and Chasidut, Talmud, Maimonides, Buber, davening and Chasidic nigunim, evolution and cosmology, sustainability, and most recently, astronomy (including telescope observations). David has smikhah (ordination) from the Jewish Theological Seminary and from Rabbi Zalman Schachter-Shalomi, and is one of the world's foremost scholars on Judaism and ecology. His book, Kabbalah and Ecology: God's Image in the More-Than-Human World, was published in2015 by Cambridge University. David has also worked as an activist and community organizer, and he founded the first Chasidic-egalitarian minyan in the world on NYC's Upper West Side, which was the inspiration for He has taught at well over 100 synagogues, communities, retreats and conferences across North America (and a few in Israel), and is published widely on ecology and Judaism.

David's teaching empowers learners to become creators of Judaism through deep study and communion with texts and tradition. He brings not only expertise in science (ecology and cosmology) and texts (midrash, Talmud, philosophy, Kabbalah and Chasidus), but also engagement with spirit (mysticism, meditation, davening and nigunim), embodiment, and ritual. His personal practice includes a focus on the "shamanic" dimension of rituals and religious practices like Shabbat and Sukkot.

David does scholar-in-residence Shabbatonim across the country, and is also available for lectures, seminars, and Jewish Studies-related editing and writing. Here are some examples of Shabbaton themes:

  • "Tsfat Shabbat" - on Chasidus, nigunim and davening, with a special emphasis on embodied prayer, including dance; may include text study of Rebbe Nachman and Shneur Zalman
  • "Kabbalah and the Exuberance of Life" - on basic concepts of Kabbalah and Kabbalistic themes that relate to ecology and issues like biodiversity, climate change, fracking, and genetic engineering; this shabbaton may also include a session on "the souls of Animals in Jewish tradition"
  • "The Passions of Maimonides" - on Maimonides's teachings in the Guide for the Perplexed related to animal rights, organic cosmology, the Gaia hypothesis, as well as his significance in medieval philosophy, and what his work teaches us about the uncensored history of science
  • "The Embodied Earth" - on the Jewish Festivals, ritual, shamanism, the Shmitah (Sabbatical) year, and the human place in the cosmos (especially relevant to Sukkot)
  • "Love Your Neighbor/Love the Stranger" - on human rights, peace, halakhah and politics; this can include contemporary issues like immigration reform or issues concerning Israel, such as the situation of the Bedouin, and study of modern thinkers like Martin Buber or Yitz Greenberg
