David's teaching focuses not only on science (ecology and cosmology), and spirit (Chasidus, Kabbalah, davening and nigunim), but also on embodiment, ritual, and the shamanic or psycho-spiritual dimension of concrete religious practices (like Shabbat and Sukkot). A further focus of his teaching is the radical empowerment of learners to create Judaism through deep study and communion with texts and tradition.

David does scholar-in-residence Shabbatonim across the country. Some examples: "Tsfat Shabbat" - on Chasidus, nigunim and davening; "Kabbalah and the Exuberance of Life" - on biodiversity and climate change, and of course Kabbalah; "The Passions of Maimonides" - on animal rights, organic cosmology, and the uncensored history of science (and of Maimonides); "The Embodied Earth" - on the Jewish Festivals, ritual, shamanism, 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 concerning Israel).
