The Nature of Sleep

So we may now say that our soul life is a life of independence, a life of which we have something like a reflection through our consciousness during our waking day life. Consciousness is a reflection of the interactions of the soul with its environment. During the waking day life we are lost to our surroundings, to something foreign, are devoted to something that is not ourselves. But during sleep—and this is the nature of sleep—we withdraw from all outer activity to work on ourselves. The comparison is apt; the ship which has served shipping while it was at sea will be rebuilt and repaired when it arrives in port.
