Donald, That's a pretty good one. It's not exactly traditionally zen, but from a Tibetan Buddhist. It's a similar thought coming from the opposite perspective to a quote on compassion attributed to a Bodhisattva who's often quoted in Western culture: "Do unto others as you would have them do unto you." - Jesus of Nazareth.
