Here are two passages from Juniper that summarize wabi-sabi:
The term wabi-sabi suggests such qualities as impermanence, humility, asymmetry, and imperfection. These underlying principles are diametrically opposed to those of their Western counterparts, whose values are rooted in the Hellenic worldview that values permanence, grandeur, symmetry, and perfection. …
Wabi-sabi is an intuitive appreciation of a transient beauty in the physical world that reflects the irreversible flow of life in the spiritual world. It is an understated beauty that exists in the modest, rustic, imperfect, or even decayed, an aesthetic sensibility that finds a melancholic beauty in the impermanence of all things.
