Following William's recent piece; I was looking through examples of a representative New Age series originating some twenty-some years ago: James Redfield's Celestine Prophecy and the follow-up volumes.
I was interested in these because of the central place Redfield gives to Synchronicity (i.e. apparent coincidences that seem meaningful); and the idea of acknowledging and being guided-by events that seem to be examples of it.
(And there are plenty of good things in Redfield's books - perhaps most of what is needed is there, somewhere or another.)
In fact, this was one of the important threads that led me to theism; since I reasoned that if synchronicity was real (as it seemed to be, in my own life) then it implied a personal God with an interest in myself personally... To make sense of synchronicity rules out a random and directionless universe, and it rules-out the idea of a reality of abstract tendencies.
At least, this is what I reasoned - but in fact Redfield doesn't go down this path of a Personal God, but keeps his discussion rooted in abstract and physics-derived concepts such as Energy, Light, Vibration and Frequency; and this is indeed typical of New Age thinking.
Such a perspective leads onto the practical conviction that the centre of religious life is therapy; and indeed Redfield was a professional (psycho) therapist, and the books are therapeutic in orientation. In other words, the centre of New Age spirituality is therapy; in other words how people feel - the books are self-help, and the social aspects are workshops and individual psychological work.
This shows the deficiency of New Age - and how it is assimilated to materialist modernity (as can be seen from the universal leftism of New Age gurus and participants). New Age is not an alternative to the mainstream meaninglessness and purposeless of publicly-shared 'objectivity - but is a strengthening of the subjective and the personally-arbitrary elements of modern life... In a sense it is a strengthened wishful-thinking within limits, and tested pragmatically in a trial and error fashion.
Because, in New Age, the ultimate reality is abstract and physics-like - because there is No personal God; this means that there is no personal moral guidance, in particular no sexual morality. And this was very important in the 'success' - and the failure - of New Age thinking.
Because sex is (probably) the second most powerful human drive (after religion) then in practice sexuality tends to take-over New Age life - and it becomes a miserable litany of promiscuity, affairs, divorces, manipulation and experimentation.
