Vipassana means “clear seeing.” The practice is simple in instruction and demanding in execution: observe sensation as it arises, moment by moment, without adding to it. What becomes evident, with sufficient stability, is Anicca, Dukkha, and Anatta — not as thoughts but as directly seen facts.
Ten-day silent vipassana retreats in the S. N. goenka lineage are among the most widely available contemplative intensives in the world. Other modern teachers — Mahasi Sayadaw, Ajahn Chah, Joseph Goldstein, Sharon Salzberg — offer the practice in related forms.
