Wabi Sabi is one of the most conspicuous and characterizing features of traditional Japanese beauty.
A comparison can be made to the Greek ideals of beauty. For example, just as the Greek ideals of beauty are held in high regard in the west, so too is the concept of Wabi-Sabi valued in Japan, holding roughly the same position in the Japanese value system.
If an object or expression can bring about, within us, a sense of serene melancholy and a spiritual longing, then the object os said to be Wabi-Sabi.
