“The secret of life is enjoying the passage of time. Any fool can do it, there ain't nothing to it.” These words were sung by James Taylor. While he probably did not have Shabbat in mind, he might as well have been talking about the heart and soul of the Sabbath: time.
What is time actually? Time is the fluid in which we all swim. Time is an intangible thing. Time cannot be found or created. Time is not an abstract concept. Time is real. Time is as real and fundamental as air is to our existence. Time is what gives events and things meaning.
