The first disciple was asked to describe what he saw. He said, "I see the trees, the branches, the leaves, the sky, the bird and its eye..."
The sage asked this disciple to wait. Then he asked the second disciple the same question and he replied, "I only see the eye of the bird."
The sage said, "Very good, then shoot." The arrow went straight and hit the eye of the bird.
Unless we focus, we cannot achieve our goal.
It is hard to focus and concentrate, but it is a skill that can be learned.
