“Sabi was refined over the years to emphasize a state of receptivity, fostered in remote natural settings. This positive aloneness was joined to the wabi appreciation of the understated and unrefined to form a phrase with deep resonance for the contemplative mind. People would dream of living in simple enlightened appreciation of nature.”
– Richard R. Powell from Wabi Sabi for Writers (pg. 7)
