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.
>From Dalai Lama,
"Compassion is the undertaking to share the karma of others." from one of
his books on Compassion. I don't remember the title.
