Many wells, one river. That is Deep Ecumenism.” —Mathew Fox

Reb Zalman z”l taught that we can and should find nourishment in traditions other than our own. He often reminded us that “you can’t get all your vitamins from one source.” He adjured us to undertake “the more intrepid exploration of deep ecumenism in which one learns about oneself through participatory engagement with another religion or tradition.”

This program is for those who want to be certified as a mashgiach/mashgichah in both the laws of Kashrut and the ever-evolving ecological sensitivity called “Eco-Kashrut.” With this certification you will be qualified to kasher and supervise a kitchen in your congregation, retreat sites, hotel kitchens, and more.

Sage-ing is the process of harvesting one's wisdom, drawn from life experience, using the art of reflection and spiritual practice. Our programs feature new approaches to the encounter with spiritual eldering. Our Core Programs and New Offerings are now online.

The defining years of my childhood were spent opening to the Divine Mysteries of this world and the Source behind those mysteries, under the sheltering guidance of my paternal grandmother. What she taught me was sourced in an ageless transmission – shared from mother to daughter for countless generations, and thought to be “secret.”
—Rabbi Nadya Gross

Rabbis Nadya and Victor Gross received joint Rabbinic Smicha from Rabbi Zalman Schachter-Shalomi, z”l, and the P'nai Or religious fellowship in 1998, recognizing their unique relationship paradigm. Since that time, their professional lives have been deeply inspired by and committed to Reb Zalman’s seminal teachings on Paradigm Shift, Sage-ing®, Deep Ecumenism and Eco-Kashrut. This commitment led to the creation of Yerusha in August 2017.
