Translated as calm abiding, shamatha is a meditative practice that cultivates mental stability, clarity, and tranquility through sustained concentration. Practitioners settle their attention on a single object, such as the breath, a mantra, or a visual form. When the mind wanders, they notice the distraction and return to the object. Theravada, Mahayana, and Vajrayana traditions all teach some form of calm abiding, often as groundwork for further practice. On its own, calm abiding pacifies mental agitation; when paired with insight (vipassana), it supports the direct understanding that leads to the weakening and eventual cessation of mental afflictions.
