The Defect In Sleep

Who has invented day? Does the same entity invented night? If so, then, the same must have invented sleep That covers us like a cloak and becomes a means To hungry to avoid hunger or provides drink to thirsty Peace to those who are disturbed Rest to those who are tired Healing to wounded And makes an equal a beggar to a king A proud to humble, all wonderful men to an ordinary But it has one defect and that is it has similarities to death Since there is little difference between a dead And a man who is asleep Is that defect created on purpose? If so, then, who is its creator? Is it that entity that never touches sleep or death?
