In our human life, not only the body as a material exists, there are also the senses and the energies which cannot be seen. The natural healing power may be one of these energies. I improved my constitution by activation of this natural healing power without depending on medicines and doctors. The practical conditions are reported here for such improvement. I was astigmatism and nearsightedness in 27 years old, and eyesight was less than 0.1, but I took off my glasses to activate my natural healing power. I get back in about 0.5 then 56 years old, daily life, without glasses, at the time of driving, use of glasses. After that, I concerned business of the subtle energy and began to use the subtle energy equipment. When I was 61 years old, I acquired a driver's license without glasses. After that I started from lumbago and a change in a body was generating arthritis one after another, but I got over those by improvement of eating habits and the environment. It's said that a gene is changed by a recent scientific announcement, but indeed my experience is the realization.
