Each day we light fires and put them out. We break things and build. We plant and harvest, tear and smooth. Six days a week we effort, tirelessly to create. In the year 200 C.E., the rabbis of the Mishna got radical. They took a list of 39 artisan techniques -- threshing, winnowing, sowing, skinning, weaving and tearing -- and transformed it from a checklist to create into an invitation to be created. Shabbat is one of these nights.
