Communitas breaks in through the interstices of structure, in liminality; at the edges of structure, in marginality; and from beneath structure, in inferiority. It is almost everywhere held to be sacred or “holy,” possibly because it transgresses or dissolves the norms that govern structured or institutionalized relationships and is accompanied by experiences of unprecedented potency.
