about Desert Rain Zen

innovative work with koans
that aims to foster a deep engagement
with awakening and individual transformation
and a lively commitment to the Bodhisattva vow
in a welcoming and encouraging practice environment

Open Source is part of the Pacific Zen School

that supplements individual koan practice
with group koan work
with an eye toward making the wisdom, richness, and transformative power
