A zerobox is a visual reminder to pause at the threshold of your door, to set to zero, recognize your own boundless completeness and connection to and of all things. (solid oak.) (Get a set of 3 to put on more of your doorposts, your car, wherever reminders to return are most useful. The writing on the back is a poetic version of the primary invocation in the Jewish tradition called The Shema.)
