Karesansui and Wabi-sabi

Quick answer：

Karesansui, also known as 'dry landscape' or 'rock garden', is a Japanese Zen garden design that features carefully arranged rocks, usually in a grid pattern, over a bed of white sand or gravel, symbolizing mountains and seas. Wabi-sabi is a Japanese aesthetic philosophy that appreciates beauty in imperfection, asymmetry, simplicity, and the transience of all things. Both concepts are deeply rooted in Japanese culture and are celebrated for their minimalist and meditative qualities.
