Hello my name is Don and I am your personal hypnotherapist, now retired. I dealt with controlling performance anxiety among athletes, musicians, public speakers, and control the parasympathetic nervous system to enhance performance. I had much success in overcoming phobias or addictions.
Training the body to breathe at six times a minute is important. Getting the process down to one breath to initiate the mind and body into a relaxed hypnogogic state makes the process an on going hypnotic self-help day to day exercise. When your breathing is controlled so is your heart rate and pressure. It is a bit like using control knobs that you can dial up or down from a relaxed state.

Other more bizarre applications were too remarkable to mention here but what I found quite satisfying was learning from thousands of people their unique personal stories. A priest might feel the same.
Post hypnotic suggestions have a shelf life but are highly useful.
They can be self aware reminders or unconscious reactions.

Be it forms of Yoga or guided imagery the quality of self control mechanisms are within your grasp whether its called therapeutic hypnosis or prayer.

btw I never believed in past life memories. I considered that stuff paranormal BS however I believe we had pre natal dreams. It is clear to me that we know far more than our conscious mind thinks it knows.
