There is nothing new in the idea of sleep. People have been told almost since the creation of the world that they are asleep and that they must awaken. How many times is this said in the Gospels, for instance? “Awake,” “watch,” “sleep not.” Christ’s disciples even slept when he was praying in the Garden of Gethsemane for the last time. It is all there.

P. D. Ouspensky (1878 – 1947)
