The time the Dalai Lama went bowling in their basement, the time a stranger showed up with exactly the $15,000 they were missing — and more behind-the-scenes stories from 50 years of IMS.

In 1975, a handful of young Americans fresh back from years of intensive practice in India and Burma pooled together $150,000 they didn't have and bought a former Catholic novitiate in rural Massachusetts. Fifty years later, the Insight Meditation Society has become one of the most consequential institutions in the history of Buddhism in the West — the place where Jon Kabat-Zinn had the idea that became Mindfulness-Based Stress Reduction, and where, as one longtime yogi put it, the whole thing has run for half a century "without any adult supervision whatsoever."

For IMS's 50th anniversary, Dan sits down with four of its founding teachers — Jack Kornfield, Joseph Goldstein, Sharon Salzberg, and Jacqueline Mandell — along with Steven Schwartz, who helped get the organization built in the first place. Together they trace the founding story, the early years of $25-a-month stipends and "window wars," the accidental birth of the mindfulness movement, and what they hope IMS looks like 1,000 years from now.
