A religion is a set of common beliefs and practices generally held by a group of people, often codified as prayer, ritual, and religious law. Religion also encompasses ancestral or cultural traditions, writings, history, and mythology, as well as personal faith and mystic experience. The term "religion" refers to both the personal practices related to communal faith and to group rituals and communication stemming from shared conviction.
