This Element introduces New Age religion. The New Age Movement is a loosely cohesive conglomerate of different spiritual currents with no common founder, leader, institution, dogma, or scripture. Because of its diversity, it may appear amorphous and incoherent at first sight. This Element emphasizes both the unity and diversity of the New Age. It approaches the phenomenon from three main perspectives: 1) the historical development of New Age religion, 2) ideas and practices associated with the New Age, and 3) the social organization of the New Age movement. It thus provides a wide-angle view that sketches out some of the main patterns that emerge from a mosaic of individual currents and actors associated with the New Age. It also highlights some of the differences within the movement by exploring some ideas and practices in depth.
