The verb "heal" must be used actively. I heal myself. A human being is healed by something. That is a very positive deed of human beings. When I listen to the music of my son, I don't experience any passive deed. I feel I am doing something positive with my son. We are looking out at the same direction. So if someone feels he is healed by the music of my son, even then I believe someone is looking in the same direction as my son. So he is positively healing himself with my son.
