The religions of the world consist of religious images and religious behaviour. The religious images of the religions from the past and of present day religions, like gods, ghosts and worshipped ancestors, concepts of guilt, dogmatic teachings and ideas of the hereafter, are generally quite well known. Religious behaviour on the other hand, the actions which believers of a specific religion do or do not do, is often not that well known. For an understanding of religion however, religious behaviour is at least as important as the religious images.
