What does it mean to be in perfect peace?

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. 

For perfect peace will not come at once. You will have to work for it.

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.

―The Judge [Last Letters from a Living Dead Man]
