In a field, there was an oak at one end, and a willow-tree at the other. Whenever a wind moved through the field, the willow swayed in the wind, while the oak remained unmoved.
When this happened, the willow said to itself, “I wish I was as strong as the Oak, instead of bending over with every breeze.“
One day a large windstorm whipped through the field. When the storm passed, and the darkness lifted, the willow looked across the field, and was shocked to discover that the oak was laying on the ground, broken. When the Gardener came into the field, the willow said, “Oh sir, what happened to the Oak? How is it that I survived the storm, weak as I am, and the Oak fell?”
The Gardener said, “Oh little willow-tree, do you not understand what happened? When a really powerful wind comes along, you can bend with the wind, and survive it. But the Oak cannot bend, and so if the wind is strong enough, it will break. For the Oak had a secret, a weakness within that no one looking at the outside could see. And the Gardener went on his way, leaving the willow to ponder what he said.
