Why love ritual?

Why love ritual.  A question can be answered in different ways.  Ritual makes us feel secure.  Visiting a moment for the umpteenth time brings serenity and a clarity that is hard to match.  It may be the stoned pot head rolling another joint, the star athlete taking his starting position, the religious adherent swaying, or kneeling, or dancing or singing in ecstasy.  It could be any of us.  It is the moment that unites us all if we can accept the validity of theirs.
