Samatha (Pāli samatha Sanskrit: śamatha शमथ; Chinese: 止; pinyin: zhǐ), "calm," "serenity," "tranquility of awareness," and vipassanā (Pāli vipassanā; Sanskrit: vipaśyanā विपश्यना; Sinhala: විදර්ශනා), literally "special, super (vi-), seeing (-passanā)", are two qualities of the mind developed in tandem in Buddhist practice.
In the Pāli Canon and the Āgama these qualities are not specific practices, but elements of "a single path," and are "fulfilled" with the development (bhāvanā) of mindfulness (sati) and meditation (jhāna) and other path-factors. While jhāna has a central role in the Buddhist path, vipassanā is rarely mentioned separately, but is usually described along with samatha.
