Certainly. The mind is a major tool for any disease. No medicine can cure any disease unless otherwise the mind is co-operating, Mental stress is keep a curtain between the medicine/treatment and our illness. Many of when got fell in illness go to doctor but once we return from the doctor after consultation and medicine, our mind is not get satisfied but our stress is increasing whether the doctor gave a correct medicine or not. Immediately we refer computer for that medicine and related diseases. In computer the usage of that particular medicine for many diseases including this patient have. But this patient immediately get mental stress that whether the doctor wrongly diagnosed his disease or wrongly given the medicine.
Some people wrongly diagnosed himself correlating with some other thing. I read in one medicine book that a man came to a doctor by saying that he dreamt as he swallowed a cat and asked the doctor to check whether the cat is in him. He checked thoroughly and told nothing found inside him. As he did not satisfied his mental stress shoot up, he went to another doctor he also said no cat found in him. With increased stress, he went to another doctor. On hearing his problem the doctor agreed to him, took an X-Ray and told him a cat is inside him and asked him to come on the next day prepared so as he can take out the cat from him. But the patient asked the doctor how he found out the cat as earlier two doctors told nothing. This doctor replied," I took the X-Ray in dark and so that the cat came to my vision". Satisfied with the reply the patient agreed to come on next day with fees. The Nurse asked the doctor why he told lie to him. Doctor calmly replied her that he told like that to release his mental stress and asked her to have a cat with her on the next day and to make it run when he nodded his head after the patient came in. Next day the patient came and the doctor told him that," I decided to take out the cat from you without any operation. But I will hit on your center head strongly. You should shout loudly by opening your mouth widely." When the patient shouted loudly, the nurse made the cat (which she hide with her) to run on the patient's vision. The patient jumped with joy and told the doctor that he only correctly cured his problem. By saying this he poured money before the doctor with joy. Both doctor and Nurse felt happy as they removed his mental stress. The patient move out but stand at the entrance and told the doctor, "Sir, I swallowed white cat but the black cat only came out, How?' Immediately the doctor and Patient got fainted. \
So, mental stress can be cured by ourselves only as not prolonging from one to another.
