Wavy Gravy once asked a Zen Roshi, "What happens after death?"
The Roshi replied, "I don't know."
Wavy protested, "But you're a Zen Master!"
"Yes," the Roshi admitted, "but I'm not a dead Zen Master."
This is about the same as my attitude about what happens after death: I don't know.
But I hope, in some small pocket of the world, that what happens after my death includes that people get together to celebrate and share memories of my life.
