The Way of Zen and Zen values of simplicity (kanso), naturalness (shizo), and refined elegance are similar values expressed in the Japanese garden, and defines Japanese rock gardens. Stones and rocks derive from the natural banks of rivers and creeks. They provide accents for distinctive garden areas, including walkways, waterfall bases, creek borders, ponds and lakes, and garden sections. Rocks and pebbles of rock gardens are raked into patterns of flowing streams, undulating waves, and accents around larger stone island or bonsai trees, and other features. Other patterns can be checkered or angled or alternating lines.
Large feature stones are grouped by themselves or they are grouped in threes with a taller boulder standing regally behind two shorter boulders, presenting balance. All three stones are generally vertical, with the taller stone in the center representing The Buddha (one who has become enlightened), and the two other stones on each side representing two Bodhisattvas (one who is “bound for enlightenment; the two stones are called sanson). They are placed next to water, a body of water or water feature, as images of water features, natural hills and/or mountain scenes.
Bodies of water are represented in the Japanese garden by a pond or lake. In the case of dry Zen rock gardens where sand and gravel represent the sea or ocean, the stones would be placed next to or in the sand/ pebble garden. The scene of ocean and sea occupying the majority of the garden space (“chisen”) originates from China, as does the garden aesthetic and spirituality of Zen Buddhism. Groups of rocks on one or more sides of the body of water in the garden may represent the seashore.
