"Prison life taught him how little one can get along with, and what extraordinary spiritual freedom and peace such simplification can bring. I remember again, ironically, that today more of us in the world have the luxury of choice between simplicity and complication of life. And for the most part, we, who could choose simplicity, choose complication. War, prison, survival periods, enforce a form of simplicity on us. The monk and the nun choose it of their own free will. But if one accidentally finds it, as I have for a few days, one finds also the serenity it brings."
