Blessings on him who invented sleep, the mantle that covers all human thoughts, the food that satisfies hunger, the drink that slakes thirst, the fire that warms cold, the cold that moderates heat, and, lastly, the common currency that buys all things, the balance and weight that equalizes the shepherd and the king, the simpleton and the sage.
