New Age, also referred to as the New Age movement or New Age Spirituality, is a spiritual movement whose purpose is to seek the Universal Truth, and for each human to reach its highest potential. The term 'New Age' was used as early as 1809, in an epic poem called 'Milton a Poem', written and illustrated by William Blake, while the elements of today's New Age first started appearing in the 1900s in metaphysical spiritual movements such as Theosophy, Spiritualism or New Thought.
In the words of Deepak Chopra:
"When your truth is aligned with the Truth of universal consciousness,
you are living your dharma...living a blissful existence.
You are "surfing the wave of Truth" - letting it propel you into the next phase of your life
while it delivers the thrill of the present moment."
New Age rejects religious doctrine and dogma. Instead it promotes individual ways of attaining truth by a large variety of means (e.g. astrology, metaphysics, esotericism, alternative medicine, sustainability,...) There are no central scriptures and New Age has no founders either. It is a spiritual movement that has developed little by little and is joined by people with similar beliefs. Some of the major influences were people like Edgar Cayce, Yogananda, Madame Blavatsky, Osho, and Deepak Chopra.
Summing up all beliefs and teachings of New Age is close to impossible.
There are simply that many. Here are a few of the major concepts:
"Truth is exact correspondence with reality."
