Rudolf Steiner: "All that we have here on Earth as feeling of reality, all that we should describe as the reality — the real existence — of human beings whom we meet here, is in its intensity like the reality of a dream compared to the immensely strong reality which we experience in the decades immediately after death and which the clairvoyant observer can experiene with us. For there, everything seems to us more real. The earthly life seems like a dream. It is as though the soul were only then awakening into the real intensity of life.... How weak is the reality of earthly life compared with that intensest life which meets us when we follow a man after his death!"
