Celebration is a confrontation involving the giving of attention to the transcendent meaning of one's actions.

Celebration is self-restraint, is attentiveness, is questioning, is meditating, is awaiting, is the step over into the more wakeful glimpse of the wonder - the wonder that a world is worlding around us at all, that there are beings rather than nothing, that things are and we ourselves are in their midst, that we ourselves are and yet barely know who we are, and barely know that we do not know all this.

Celebration is not to be endulged in overly hastily — don't whistle until you're out of the woods.

Celebration is unwise before a thing has ended — Do not praise the day before the nightfall.

Discovery is seeing what everybody has seen and thinking what nobody has thought.

Discovery is the ability to be puzzled by simple things.
