Get rid of all that is unnecessary. Wabi-sabi means treading lightly on the planet and knowing how to appreciate whatever is encountered, no matter how trifling, whenever it is encountered. In other words, wabi-sabi tells us to stop our preoccupation with success -- wealth, status, power, and luxury -- and enjoy the unencumbered life. Obviously, leading the simple wabi-sabi life requires some effort and will and also some tough decisions. Wabi-sabi acknowledges that just as it is important to know when to make choices, it is also important to know when not to make choices: to let things be. Even at the most austere level of material existence, we still live in a world of things. Wabi-sabi is exactly about the delicate balance between the pleasure we get from things and the pleasure we get from freedom of things.
Things wabi-sabi have no need for the reassurance of status or the validation of market culture. They have no need for documentation of provenance. Wabi-sabi-ness in no way depends on knowledge of the creator's background or personality. In fact, it is best if the creator is no distinction, invisible, or anonymous.
Pare down to the essence, but don't remove the poetry.
Leonard Koren, from Wabi-Sabi: For Artists, Designers, Poets & Philosophers
