Not much is written specifically about new age/newness from a psychodynamic pespektiv. After Freud's stiss with religion almost a hundred years ago, many seem to want to avoid the subject. One who, however, has set out to try to describe this modern spirituality from a Freudian angle is Faber. In his book "New Age Thinking" (1996), he writes:

"From the psychoanalytic angle, three items stand out clearly; first, we have an overarching presence of infantile omnipotence, the egocentric, unconscious belief in one's unlimited powers […]; second, we have the urge to fuse regressively with the environment, to attach oneself to the surrounding world (universe) in a way that denies, erases, cancels out the ever-present sense of separation which the cronologically mature individual must cope with during the course of his days on the planet; third, we have a longing for narcissistic inflation, the longing to go about in the belief that one is somehow magical, wonderful […] as opposed to being simply another regular person in the world. (Faber)
