To solve devil(ill)(socially-good character by personally-bad character),one should be devil(ill) to devil(ill) within. That means invoking healer(devil) within by devil(healer) is the best medical treatment in world. Pl.note that if you feel pain and suffering by meditation in any part of human body,pain and suffering will be induced and felt in that part of body. In other words,devil(ill) exists in one's mind.But it's manifestation is in one's body. So without making mind as socially-bad character by personally-good character,one can't heal devil(ill) within.
