One of the great stories in Eastern Philosophy concerns two animals: a scorpion and a frog. One day a scorpion was trapped on the shore of a river, and he needed to get to the other side. He asked a frog he saw swimming out in the water to come get him and take him across.
The frog refused. “You are a scorpion,” the frog said. “If I take you on my back, you’ll sting me.”
The scorpion said that was foolish, of course he wouldn’t sting him because then he would drown in the river and die, too. The frog thought about it, and agreed that it wouldn’t make sense. He let the scorpion on his back, and then started paddling across the river.
When the frog was halfway out, the scorpion stung him. As the frog was dying and they both began to slip under the water, he asked the scorpion why he did it. “It’s my nature. I am a scorpion,” he said. “And scorpions sting.”
The essential interpretation of the story is that every creature has a nature, and you cannot argue against it, or expect it to change. You must accept it for what it is. For example, your dog will only bark; he will never talk to you in English. To expect otherwise would not only be crazy, but it would leave you disappointed for the rest of your life.
So, see things as they are, not as you wish them to be and be brave enough to face the truth.
