Muin Soin

Muin Soin was a Rinzai Zen master who served in the school's transmission lineage. He maintained the tradition's emphasis on koan practice and contributed to the Rinzai school's continuity during his period of activity.

Soin's place in the Rinzai lineage represents the tradition's emphasis on the personal transmission of insight from teacher to student. The Rinzai school holds that genuine understanding can only be confirmed through the direct encounter between master and student, and that this encounter must be grounded in the shared practice of zazen and koan contemplation.
