We have to make the preparation now before we are imprisoned . . . I personally use an exercise. I live in the United States of America. Can you imagine what an American supermarket looks like? You find there many delicious things. I look at everything and say to myself, “I can go without this thing and that thing; this thing is very nice, but I can go without: this third thing I can go without, too.” I visited the whole supermarket and did not spend one dollar. I had the joy of seeing many beautiful things and the second joy to know that I can go without.
