What you're looking at is a Shinto philosophy on life. Wherein everything you do can be done with the "zest" of art.
I can't really call my "Art" form an art form, until I can prove to lay claim to it, at the very least. Performance Art, wherin you "sign" your work by having some people present while you're doing it is only "Signed" by that very fact.
Crop Circles aren't art until someone lays claim to it. Egyptian carvings are historical records, and the Caves of Altamira are a lesson in archeology , not art.
