Let us try to explain this point from the scientific point of view. According to new discovery, such pain can be cured through some chemicals produced in our body. A large number of chemicals are produced in our brain and the sushumna reduce the pain. When a person takes very sincerely to the path of devotion, he becomes more and more detached from the worldly affairs. He goes into deep contemplation and he becomes oblivious to the pain resulting from his disease. Such pain relieving condition is the result of kayotsarga.
In the state of kayotsarga, every kind of pain is forgotten. In this context, Mahavira’s statement that kayotsarga brings relief from all sufferings appears very significant and valuable. Whenever there is tension, pain would grow. There is a close connection between tension and pain. As the tension decreases, pain would decrease too. As you relax the body, pain would disappear. Kayotsarga is the most important practice, which enables our body to produce the chemicals it is required to produce.
