From Wabi-Sabi: for Artists, Designers, Poets and Philosophers by Leonard Koren
Wabi-sabi [wikipedia definition] 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 from things.
The simplicity of wabi-sabi is best described as the state of grace arrived at by a sober, modest, heartfelt intelligence. The main strategy
of this intelligence is economy of means. Pare down to the essence,
but don’t remove the poetry.
