Buddhism contains the world's most developed and diverse collection of meditation practices, accumulated over 2,500 years across dozens of traditions. The Buddha's original teachings, recorded in the Pali Canon, describe two complementary practices: samatha (calm abiding) and vipassana (insight). Samatha practices develop concentration and tranquility; vipassana practices develop clear seeing into the nature of experience. Theravada, Mahayana, and Vajrayana Buddhism each developed distinct meditation systems — from the breath awareness of Theravada to the koan practice of Zen to the elaborate tantric visualizations of Tibetan Buddhism — all aimed at the common goal of liberation from suffering.
