What does the idea of the gentle heart suggest to you? CAMPBELL: One that is capable of—well, the key word for me is compassion. MOYERS: Which means? CAMPBELL: Suffering with. “Passion” is “suffering,” and “com-” is “with.” The German word really gives it in a clearer way: mitleid, “with” (mit) “sorrow or suffering” (leid). The essential idea was to test this man to make sure that he would suffer things for love, and that this was not just lust.
