“Apparitions are, so to speak, shreds and fragments of other worlds, the first beginnings of them. There is, of course, no reason why a healthy man should see them, because a healthy man is mainly a being of this earth, and therefore for completeness and order he must live only this earthly life. But as soon as he falls ill, as soon as the normal earthly state of the organism is disturbed, the possibility of another world begins to appear, and as the illness increases, so do the contacts with the other world, so that at the moment of a man's death he enters fully into that world.”
