Years ago I heard the following story at a motivational business seminar. It stuck with me and I've used it many times. It's called 'Muddy Road'
"Tanzan and Ekido were once travelling together down a muddy road. A heavy rain was falling. Coming around a bend they met a lovely girl in a silk kimono and sash, unable to cross the intersection. 'Come on girl' said Tanzan at once. Lifting her in his arms, he carried her over the mud. Ekido did not speak again until that night when they reached a lodging temple. Then he could no longer restrain himself. 'We monks don't go near females' he said to Tanzan, 'especially not young and lovely ones. It is dangerous. Why did you did that?'
"I left the girl there," said Tanzan. "Are you still carrying her?"
