Neil French's book called 'Successful Hypnotherapy' is available from this site as a download.
The concept of Hypno-analysis as he created it in the late nineteen seventies has been taught to thousands throughout Europe and the world.
Neil French was influenced strongly by the writings of Sigmund Freud but became convinced that Freud had missed the very 'Alchemist's Stone' he was searching for by abandoning his use of hypnosis.
The version of Hypno-analysis that Neil French produced has stood the test of time and has been instrumental in helping many multi-thousands of people achieve psychological growth and relief from distressing symptoms.
This interpretation of hypno-analysis was unique. His discovery that 'free association' within the 'state' of hypnosis would lead the person to a cathartic release from 'repressed' or concealed trauma was totally revolutionary.
Neil French discovered, possibly/probably even invented, the concept of hypno-analysis. Certainly he created the concept of free association within hypnosis.
