My Favorite Zen Koan
A man walking across a field encounters a tiger. He fled, the tiger chasing after him. Coming to a cliff, he caught hold of a wild vine and swung himself over the edge. The tiger sniffed at him from above. Terrified, the man looked down to where, far below, another tiger had come, waiting to eat him. Two mice, one white and one black, little by little began to gnaw away at the vine. The man saw a luscious strawberry near him. Grasping the vine in one hand, he plucked the strawberry with the other. How sweet it tasted!
Zack Parsons sent me this over IM when I was in college. I never knew why but that could describe most of our conversations. It moved me so much that I have, to this day, never forgotten it.
