A Japanese Meditation Garden

Water, in Japanese gardens, can either be real or imagined. Fountains, like this tiered stone one in Diane's garden, can enhance the feeling of calm through the sound of water. But even without water, perfect placement of rocks can create the illusion of a flowing stream. "While viewers imagine water, they're free of worry," Diane says. "Their brain gets a rest, and that rest period could be called meditation."
