I once met a Zen-trained painter in Japan, in his 90s, who told me that suffering is a privilege, it moves us toward thinking about essential things and shakes us out of shortsighted complacency; when he was a boy, he said, it was believed you should pay for suffering, it proves such a hidden blessing.
