A spontaneous vision of a rotting corpse became Ajahn Mun’s meditation object, eventually transforming into a translucent disk that spawned endless images. After three months he realized this outward-focused concentration left him unbalanced and oversensitive. Turning attention inward to body contemplation, he finally attained stable calm, learning the cost of practicing without a teacher’s guidance.
