From Hell to Heaven
There is an ancient Zen scroll that shows heaven and hell. In hell, the hungry ghosts are all sitting at a great banquet table filled with all kinds of delicacies, trying to feed themselves with very long spoons. But no matter how hard they try, they cannot reach their mouths.
In heaven, the hungry ghosts are sitting around the same banquet table. But these hungry spirits are feeding each other with their long spoons, so that they all can eat.
This is the way to transform our world from a hell to a heaven. Only when we offer a portion of our food to our fellow hungry ghosts can we satisfy our own deepest hunger.
— Bernard Tetsugen Glassman, Instructions to the Cook
Note: Hungry ghosts were greedy, miserly and selfish when they were alive. Now they are invisible, but still starving.
