The art of Karesansui

Quick answer：

Karesansui, also known as dry landscape or Zen rock garden, is a traditional Japanese garden style that uses carefully placed stones, gravel, and sometimes moss to represent a landscape in miniature. It emphasizes minimalism and the importance of balance and harmony. The practice of karesansui involves the selection and arrangement of stones to create naturalistic scenes such as mountains, rivers, and islands, often with a sense of water suggested by raked gravel patterns.
