Anapanasati

Ānāpānasati (Pali; Sanskrit: ānāpānasmṛti), meaning "mindfulness of breathing" (sati means mindfulness; ānāpāna refers to inhalation and exhalation), is the act of paying attention to the breath. It is the quintessential form of Buddhist meditation, attributed to Gautama Buddha, and described in several suttas, most notably the Ānāpānasati Sutta (MN 118).

Derivations of anāpānasati are common to Tibetan, Zen, Tiantai, and Theravada Buddhism as well as Western-based mindfulness programs.
