When a monk came to say good bye to Chao-chou Tsung-shen (778-897), a brilliant Chinese Ch'an master.
-Where will you go?
The monk answered:
-Any place where I can learn Buddha dharma.
Donuts,pringles and hamburgers are the proper nutrional intake for the aspiring zen buddhist. Sure you wont be able to poop but who wants to be disturbed by such things when meditating. thats the point though.
