Most of Them stayed with us only through that critical period of our history; a few still remain to hold the highest offices of the Great White Brotherhood until the time when men of our own evolution shall have risen to such a height as to be capable of relieving their august Visitors.
The evolution lying before us is both of the life and of the form; for in future rounds, while the egos will be steadily growing in power, wisdom and love, the physical forms also will be more beautiful and more perfect than they have ever yet been.

We have in this world at the present time men at widely differing stages of evolution, and it is clear that there are vast hosts of savages who are far behind the great civilized races of the world--so far behind that it is quite impossible that they can overtake them.

Later on in the course of our evolution a point will be reached at which it is no longer possible for those undeveloped souls to advance side by side with the others, so that it will be necessary that a division should be made.
The proceeding is exactly analogous to the sorting out by a schoolmaster of the boys in his class.

During the school year he has to prepare his boys for a certain examination, and by perhaps the middle of that school year he knows quite well which of them will pass it.

If he should have in his class some who are hopelessly behind the rest, he might reasonably say to them when the middle period was reached: "It is quite useless for you to continue with your fellows, for the more difficult lessons which I shall now have to give will be entirely unintelligible to you.
