If those who are sick and in pain can sleep they are happy. Then all their pain is gone. If they can only sleep they feel they can endure all else. They will ask the doctor to give them anything to make them sleep. If a person were offered a king's palace and every enjoyment, every luxury, the best surroundings, the best dishes, on condition that he should not sleep, he would say, 'I do not want it; I prefer my sleep!'
