What are the Zen rules?

Answer:

A principle feature of Zen is its training in the instantaneous appreciation of and appropriate reaction to events without formal logical analysis.
As a consequence it would be impossible to formulate "Zen Rules" without negating the purpose of the training.
"What are the Zen rules?" would make a good koan.
