New Age

New Age is applied to 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 things that are stereo typed for New Age beliefs are used by so many different people weather it be for religious or everyday life use.
