We all could use a time out. Even when the electricity goes out, time goes on. We can't stop it. We can't even hope to contain it. We can sanctify it.
Technological civilization is man's conquest of space.
The meaning of the Sabbath is to celebrate time rather than space. And God blessed the seventh day and made it holy. In the beginning, time is holy. There is no mention of a sacred place, only sacred time. As Heschel and others have pointed out, the Sabbath day was the first cathedral, a portable cathedral in time.
