The principles of Zen aesthetics found in the art of the traditional Japanese garden, for example, have many lessons for us, though they are unknown to most people.

Below are just seven design-related principles (there are more) that govern the aesthetics of the Japanese garden and other art forms in Japan. Perhaps they will stimulate your creativity or get you thinking in a new way about your own design-related challenges.
