Some Thoughts on Sabbath...

From A Geography of Time:

God devoted six days to creating the heaven and earth. Then on the seventh, the work is finished - not by building a holy place, but by creating a sacred time. Although the world was created in the first six days, its survival depends upon the holiness of the seventh. What was created on the seventh day? Tranquility, serenity, peace, and repose. 

"Six days a week we seek to dominate the world, on the seventh we seek to dominate the self... In the tempestuous ocean of time and toil there are islands of stillness where man may enter a harbor and reclaim his dignity. The island is the seventh day, the Sabbath, a day of detachment from things, instruments and practical affairs as well as of attachment to the spirit." ~Abraham Herschel
