Hi Sangita You are not being unrealistic when you believe that we all possess the power to heal ourselves. The mind body connection is a powerful tool indeed. I have learned so much about this since my diagnosis. I practice visualizations first thing every morning and last thing every night. I have learned a great deal from a young Canadian energy healer's books on the subject and I have also attended four of his workshops. His work has been authenticated by the scientific community and he holds workshops in many different countries now often presenting with such notables as Dr. Edgar Mitchell /former astronaught. Hopefully his website will be allowed here. www.dreamhealer.com
along with this one which contains many, many video testimonials on successful outcomes.
