If it were possible to place ourselves in thought at a centre in space from which we might see the course of evolution, from which we might study the history of our chain of worlds rather as they might be seen in imagination, in picture, than in the appearance that they present as physical, astral and mental, I think that thus looking outwards on these evolving groups, this evolving humanity, we might figure the whole in a picture. I see a great mountain standing in space, with a road that winds round the mountain, round and round until the summit is reached.
