Two Lineages, Two Methods

Vipassana and zazen both descend from the meditative discipline attributed to the Buddha, but they reached their present form through separate historical routes and now differ noticeably in method. Vipassana, insight meditation, is the Theravada tradition's systematic observation of breath and the arising and passing of bodily sensation, and the form most widely taught today owes a great deal to a twentieth century lay revival in Burma, associated above all with the teacher Mahasi Sayadaw and later popularized worldwide through students such as S. N. Goenka, whose residential courses introduced the practice to audiences with no monastic background.

Zazen followed the opposite route geographically, carried from India through Chan Buddhism in China into Japan, where it split into distinct schools with different emphases: the Soto school associated with just sitting, shikantaza, meditation without an object or goal, and the Rinzai school's use of koans, paradoxical questions a student works with under a teacher's direction to break ordinary logical thought. Vipassana centers on sustained, gradual observation; koan practice centers on a sudden breakthrough forced by an unanswerable problem. Both traditions describe themselves as returning to the Buddha's own method, and both have developed substantial modern lay followings far from their monastic origins, but a practitioner moving from one to the other is learning a genuinely different technique, not a regional variant of the same one.
