Tradition is not necessarily a system developed by anybody, but the root of tradition is the natural understanding of things are they are. It is based on seeing and everybody agreeing that the sky is blue and the grass is green. Tradition is that way, rather than being anybody’s established law and order or personal opinion. Therefore, genuine tradition is common sense at its best.
