Diagnostic Trance The concept behind a diagnostic trance is that client is best placed to find, locate and describe the root of their own physical, emotional or psychological discomfort. In addition the client is in a better position than the therapist to identify the best way of removing the discomfort. It is a Neo-Ericksonian approach to healing designed to create change quickly and efficiently as possible. In essence, it’s a proven technique (documented in Hypnotherapy Scripts by Havens & Walters) that makes use of the clients own unconscious mind for diagnosis and resolution. Since the unconscious mind has the responsibility for our well being and good health. it should come as no surprise that it is capable of providing the most effective solutions.
