But ritual involves structure and discipline, even that as simple as the ritual of brushing one's teeth in the morning or showering or cleaning up. Discipline, structure and repetition are not exactly the catchwords of the 90's. So it may be hard to make a case for it. The stricter the rules and the more structured the ritual, the more it will appeal to those who have no structure at all or feel rudderless.
Violence is the open expression of powerlessness.
The child's tantrum or an old person's harsh grumpiness are mild expressions of powerlessness. Anyone who feels cornered or trapped must either strike out, or break away. Or they may turn the anger inward and die in some way, lose their fire or become depressed. Hearing these words and the same music over and over sets up a vibratory field that seems to have an empowering and healing effect on people, especially since many others are present. Your theory certainly has seeds worth exploring.
