New Age is a range of spiritual or religious beliefs and practices which rapidly grew in the Western world during the 1970s. Precise scholarly definitions of the New Age differ in their emphasis, largely as a result of its highly eclectic structure. Although analytically often considered to be religious, those involved in it typically prefer the designation of spiritual or Mind, Body, Spirit and rarely use the term "New Age" themselves. Many scholars of the subject refer to it as the New Age movement, although others contest this term and suggest that it is better seen as a "milieu" or "zeitgeist".
