...Two monks were walking side by side down a muddy road when they came upon a large puddle which completely blocked the road. A very beautiful lady in a lovely gown stood at the edge of the puddle, unable to go further without spoiling her clothes.
Without hesitation, one of the monks picked her up and carried her across the puddle, set her down on the other side, and continued on his way. Many hours later when the two monks were preparing to camp for the night, the second monk turned to the first and said, "I can no longer hold this back, I'm quite angry at you! We are not supposed to look at women, particularly pretty ones, never mind touch them. Why did you do that?" The first monk replied, "Brother, I left the woman at the mud puddle; why are you still carrying her?"
