Karesansui, also known as 'dry landscape,' is a Japanese Zen rock garden that utilizes stones, sand, and moss to represent a natural landscape without water. The method of arranging a karesansui involves selecting the right stones, arranging them to represent mountains, water, and sometimes plants, and raking the sand in patterns to represent flowing water. It is a form of Japanese garden design that emphasizes simplicity, natural elements, and the cultivation of mindfulness.
