Shuva: Returning to Ourselves

Sunday, November 16, 2025
Bay Area, California

Physician-supported, trauma-informed, and Jewishly-rooted small group day-long ketamine retreats, with in-depth preparation and integration support.

The gates are never completely closed.

Though the High Holidays have passed, the work of the soul continues. According to the Jewish mystical calendar, the teshuva season doesn’t end with Yom Kippur—or even with Sukkot. The true end of the journey of return unfolds quietly in the deepening stillness of Kislev, the month of dreams, darkness, and hidden light.

Judaism doggedly insists that no matter how far we’ve drifted—from our bodies, our values, our relationships, or the voice of our own inner knowing—the road to return is always unfolding at our feet. This path of reconnection, known as teshuva, is not merely a moral reckoning. It is a cosmic movement, a sacred rhythm pulsing through all of creation.

In this moment of rising tension and fragmentation within Jewish life—personal and collective—we are called not just to endure, but to soften. To slow down. To listen inwardly. And to find our way home, again.

This ketamine-assisted retreat offers a sacred container to continue the soul-work of the High Holidays—through deep rest, somatic integration, gentle ritual, and altered states of consciousness. In the long nights of Kislev, when the world contracts and the hidden spark begins to flicker, we invite you to join us in returning to the root. To tend the embers. To remember who you are.

Because the season of teshuva isn’t over. It’s only ripening.

To facilitate this journey, we are honored to offer Shuva, our physician-supported, trauma-informed, and Jewishly-rooted small group ketamine retreat. We believe that psychedelic work done within a communal context – here in a traditional group of at least ten people – can be an incredibly effective opportunity to rediscover ourselves and begin to heal the burdens we are holding as Jews.

Working with ketamine holds great potential for deep healing and personal growth. When approached with respect and guidance, ketamine-assisted experiences can facilitate profound insights, emotional healing, and a deepened sense of connection to oneself and the world. As interest in this field grows, it is essential to prioritize and promote safety, legality, and ethical practices to best serve our community, while providing and modeling a uniquely Jewish approach to psychedelic work.

Testimonials

“Joining Shefa for my first ketamine ritual was a deep and impactful experience. The entire experience, from welcome calls to taking the medicine and integrating the revelations, was extremely professional - but also profound and spiritual. The beauty of the medicine allowed me to tackle issues around family, control, Jewish spirituality, and more, in clarifying and new ways. Rabbi Zac and the rest of the staff were empathetic experts throughout and guided us in a beautiful way to shared and individual insights. Highly recommend!”

“The Shuva retreat was profound and meaningful to me. The team was top notch and took great care in providing a safe, meaningful and community-oriented medicine journey that was book ended with well organized preparation and integration meetings. The journey took place at the beautiful [farm] which further provided a connection to nature and the land. I enjoyed connecting with the other participants and learning about their individual journeys. Through this experience, I was able to gain deeper clarity on how to attain peace in my key relationships and the confidence that I hold the key to make that happen. Thank you for this transformative experience of returning to my own and true self.”

-S.S.

“Shefa gave me my first ever ketamine experience and my first ever group psychedelic experience simultaneously. Every step of thee way was full of such care - from preparation to intention setting, alignment to spiritual purpose and attention to the body, on the day of our journey and in the integration afterwards. I would not have expected how profoundly comforting it was to dip into direct experience with the Divine Oneness in a Jewish container, but now that I have experienced it, the power of a spiritual community has an entirely new meaning.”
