My father said at a farbrengen: G‑d created the universe and all physical objects yeish mei'ayin, something from nothing. Jews must transform the "something" into "nothing,"1 transform the material into spiritual.2 The avoda of turning the physical into spiritual and making the physical into an instrument for the spiritual, is a personal obligation. Every single person, individually, is required to do this.
