“ For when a man sees that he is far from Hashem Yitbarakh, etc., this is like sleep, which is one sixtieth of death, and when he seeks and asks and finds in himself some good point still, and livens and rejoices himself and wakes himself to the service of Hashem Yitbarakh, through this — this is like waking from sleep. ”
