Thresholds

John O’Donohue:
Well, I think that the threshold — if you go back to the etymology of the word “threshold,” it comes from “threshing,” which is to separate the grain from the husk. So the threshold, in a way, is a place where you move into more critical and challenging and worthy fullness. And I think there are huge thresholds in every life.
