Zen Garden

The Japanese rock garden or "dry landscape" garden, often called a zen garden, creates a miniature stylized landscape through carefully composed arrangements of rocks, water features, moss, pruned trees and bushes, and uses gravel or sand that is raked to represent ripples in water.
Zen is a Japanese school of Mahayana Buddhism emphasizing the value of meditation and intuition rather than ritual worship or study of scriptures. Zen in Japan is meditation in India.
