The difference between psychotherapy and New Age is explaned below:
"A psychotherapy is a treatment technique for mental or emotional disorders. There are many types of psychotherapy. Some have been empirically tested and are known to be very effective, such as cognitive therapy. Many New Age therapies, however, are little more than a mixture of metaphysics, religion and pseudoscientific "insights". There may be reasonable disagreements over what constitutes successful therapy, but successful therapy should not require one to believe in God, reincarnation, alien abductions, possession by entities, inner children, Primal Pains, channeling, miracles, or any other metaphysical, religious or pseudoscientific notion."
