The fact of reincarnation, then, is taken for granted, for not one of us could possibly tread the whole of that long course, could reach divine perfection, in the limits of a single life. But our man of the world need not know of reincarnation. He knows it in his spiritual memory, although his physical brain may not yet have recognized it, and his past, which is a fact, will push him onwards until Spirit and brain are in fuller communication, and that which is known to the man himself becomes known in the concrete mind.
