A spiritual practice or spiritual discipline (often including spiritual exercises) is the regular or full-time performance of actions and activities undertaken for the purpose of inducing spiritual experiences and cultivating spiritual development. A common metaphor used in the spiritual traditions of the world's great religions is that of walking a path. Therefore, a spiritual practice moves a person along a path towards a goal. The goal is variously referred to as salvation, liberation or union (with God). A person who walks such a path is sometimes referred to as a wayfarer or a pilgrim.
