A holy man was engaged in his morning meditation under a tree whose roots stretched out over the riverbank. During his meditation he noticed that the river was rising, and a scorpion caught in the roots was about to drown. He crawled out on the roots and reached down to free the scorpion, but every time he did so, the scorpion struck back at him. An observer came along and said to the holy man, 'Don't you know that's a scorpion, and it's in the nature of a scorpion to want to sting?' To which the holy man replied, 'That may well be, but it is my nature to save, and must I change my nature because the scorpion does not change his.'
