Ānāpānasati, meaning "mindfulness of breathing", 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.

Sati, literally "memory" or "retention", commonly translated as mindfulness, "to remember to observe," is an essential part of Buddhist practice. It has the related meanings of calling to mind the wholesome dhammas such as the four establishments of mindfulness, the five faculties, the five powers, the seven awakening-factors, the Noble Eightfold Path, and the attainment of insight, and the actual practice of maintaining a lucid awareness of the dhammas of bodily and mental phenomena, in order to counter the arising of unwholesome states, and to develop wholesome states. It is the first factor of the Seven Factors of Enlightenment. "Correct" or "right" mindfulness is the seventh element of the Noble Eightfold Path.
