The deeper meaning beneath the superficial is a recurrent theme in traditional Japanese culture. In the art of garden design, it is actually given a name, hiegakure, which means "that hidden from ordinary sight." The average shlub strolls through a Japanese garden gawking at the sights, entirely unaware of the paths beneath his feet. To the connoisseur, however, these same paths offer a lifetime of study and appreciation. Here the paths are smooth, hurrying one along. There, the stones are rough, irregular, or stepped, causing the visitor to slow down, something planned by the garden's designer, who may have wanted visitors to pause at a certain point.
