Your Theta Healing practitioner will use energy testing or muscle testing to check for the existence of the limiting belief patterns. Muscle testing is a simple technique which is used to effectively check the subconscious mind of the client to see if the limiting belief is present.
It is also possible to pull radiation and other environmental toxins from the body using a similar process. Your practitioner will scan your energetic field and clear you of any of these things should they be present. Physical Healings and Viewing Inside the Body: Medical Intuitive
