Quotation by Johan Huizinga

Let us consider for a moment the following argument. The child plays in complete—we can well say, in sacred—earnest. But it plays and knows that it plays. The sportsman, too, plays with all the fervour of a man enraptured, but he still knows that he is playing. The actor on the stage is wholly absorbed in his playing, but is all the time conscious of "the play." The same holds true of the violinist, though he may soar to realms beyond the world. The play-character, therefore may attach to the sublimest forms of action. Can we now extend the line to ritual and say that the priest performing the rites of sacrifice is only playing? At first sight it seems preposterous, for if you grant it for one religion you must grant it for all. Hence our ideas of ritual, magic, liturgy, sacrament, mystery would all fall within the play concept.
