To be selfish all are selfish.
橡树和伐木工
The Oak and the Woodcutters
伐木工们在砍一棵高大的橡树。他们借助于用橡树做成的楔子，不费力气地撑开了橡树的树干。橡树叹了一口气，说：“我毫不在意砍向我的斧子，可是悲哀的是，你们用那些我的身体制成的楔子来把我劈开。”
来自自身的痛苦更难以承受。
The Woodcutter cut down a mountain Oak and split it in pieces，making wedges of its own branches for dividing the trunk. The Oak said with a sigh，“I do not care about the blows of the axe aimed at my roots，but I do grieve at being torn in pieces by these wedges made from my own branches.”
