Peek: to peer like a bird out of its nest; a sly energy, used for making quick, appraising glances out of a secure position, before slyly withdrawing, only, perhaps, to glance again. One of the playful energies of the world. This is the energy at play when the sun peeks behind clouds or mountains peek from behind their foothills. The counter spell for peeking is to boo, a short, half-courageous sound perfectly matched to peeking. The game peek-a-boo is a playful integration of both energies, and references the courage small children need if they are to meet a goose on the path, and the sly half-courage of the geese meeting them, back and forth forever. Lots of fun!
