THREE TREASURES SANGHA of the Pacific Northwest (TTS) is a lay Zen group located in Seattle, Washington. TTS is affiliated with the Diamond Sangha, an independent lineage founded by Robert Aitken Rōshi, dharma heir in the Sanbō Kyōdan (Harada-Yasutani-Yamada) lineage.

Our form is derived from Japanese Zen tradition, favoring simplicity. While we focus on individual sitting meditation (zazen), we also recite texts (sutras) together. Talks by teachers and private interviews with them provide a chance to ask questions and to refine our understanding. Our practice emphasizes paying attention experience to foster concentration and clarity of mind.

All aspects of Zen practice are designed to foster immediate engagement with the boundless totality available to us all — it is both personal and engaged with community and the world in which we live. We warmly invite you to join us.

Getting Started with Three Treasures Sangha

You do not need to be a member of Three Treasures Sangha to sit zazen with us. If you’re a beginner, though, we do ask that you attend an orientation with us about how to sit zazen.

You can learn more about opportunities to practice with us the Our Practice page.

If you’d like to become a member please visit our Join Us page.
