wabi-sabi, 侘寂

[MarkBruns]

... a concept derived from the Buddhist teaching of the three marks of existence (三法印, sanbōin), specifically impermanence (無常, mujō), suffering (苦, ku) and emptiness or absence of self-nature (空, kū).

Characteristics of wabi-sabi aesthetics and principles include asymmetry, roughness, simplicity, economy, austerity, modesty, intimacy, and the appreciation of both natural objects and the forces of nature.
