About Zen gardens

Quick answer：

Zen gardens, also known as Karesansui in Japanese, are traditional Japanese rock gardens that use rock, sand, and often moss to represent natural landscapes. They emphasize simplicity and are a key element of Japanese Zen Buddhist culture. The concept originated in China and was introduced to Japan in the 12th century. Zen gardens are designed to evoke a sense of peace and meditation, often with elements like raked sand to represent water.
