世有无妄之福，又有无妄之祸。
译文：世人有时会遇到意想不到的福运，有时也会遇到意外的灾祸。
我们地球的过去历史必须通过现在可以看到的现象来解释。
The best moments in our lives are not the passive, receptive, relaxing times… The best moments usually occur if a person’s body or mind is stretched to its limits in a voluntary effort to accomplish something difficult and worthwhile.
