451. the tortoise’s second kōan

it is good to have lettuce. but if you eat a head of lettuce, you do not have it anymore. to eat your lettuce and have it, too, is a great dream. in fact, i had it last night. i dreamt that i ate a head of lettuce, and it was delicious, and then when i awoke i saw that very head beside me, uneaten. i thought about eating it then, but instead i just went back to sleep.
