The Eagle Wounded by an Arrow
Long ago, on the peak of high mountains, there was a large eagle searching for prey with sharp eyes. As the eagle spread its wide wings and soared in the sky, a hunter hid in the valley. The hunter drew his bow and shot a sharp arrow toward the eagle. The sharp arrow flew quickly and stuck into the eagle's body. Wounded, the eagle flapped its wings in pain and fell to the ground.
Desperately, the eagle looked closely at the arrow stuck in its chest. It saw that a feather from its own wing was attached to the back of the arrow. "What wounded me was not my enemy, but an arrow made from my own feather," murmured the eagle. Being struck by a weapon carrying parts of itself felt heavier to the eagle than anything else. "Harm coming from a stranger would hurt my body, but the pain given by my own piece burned me," it said.
As the eagle drew its last breath, it faced this bitter truth. Sometimes the greatest harm to a person comes from what is closest to them or a part of themselves. A person's greatest enemy often comes from within themselves. Harm coming from someone considered a friend is the heaviest. As you sow, so shall you reap.
A foolish head makes the feet suffer. A stone thrown by a friend does not break the head. A person is hurt most by their own piece. As the tree said to the axe: If your handle were not from me, I would not fall.
