He who wants to enter the holiness of the day must first lay down the profanity of clattering commerce, of being yoked to toil. He must go away from the screech of dissonant days, from the nervousness and fury of acquisitiveness and the betrayal in embezzling his own life. He must say farewell to manual work and learn to understand that the world has already been created and will survive without the help of man. Six days a week we wrestle with the world, wringing profit from the earth; on the Sabbath we especially care for the seed of eternity planted in the soul. The world has our hands, but our soul belongs to Someone Else. Six days a week we seek to dominate the world, on the seventh day we try to dominate the self.
Abraham Joshua Heschel
