Bernd, there is this famous zen koan:
When Banzan was walking through a market he overheard a conversation between a butcher and his customer.
"Give me the best piece of meat you have," said the customer.
"Everything in my shop is the best," replied the butcher. "You cannot find here any piece of meat that is not the best."
At these words Banzan became enlightened.
I don't understand it. What lead him to enlightenment? The butcher was lying, there are bad and worse pieces, some have more meat, some have more fat, some are less fresh. The butcher was just trying to sell more.
