What recruits its population from below?

You who have followed me from those early days when I wrote you letters from the lower astral world, describing, as a traveller in a strange country, the things I had seen―

You who followed me through the hells of astral turmoil during the early months of the war, follow me yet a little further. 

I will show you the way as it has been shown to me. 

And you will walk in that way, though stumbling at first, and groping for the thread of purpose through the labyrinth of reconstruction in the days that shall be called days of peace. 

For perfect peace will not come at once. 

You will have to work for it, as you have worked for triumph in war. 

But if you have faith, you will ride the stormy waters into the haven of a new earth. 

And a new heaven will spread above the earth, for heaven is largely peopled from below―

It recruits its population from below.
