你在凝视深渊，深渊也在回望

其实人跟树是一样的，越是向往高处的阳光，它的根就越要伸向黑暗的地底。

But it is the same with man as with the tree. The more he seeks to rise into the height and light, the more vigorously do his roots struggle earthward, downward, into the dark, the deep - into evil.

——尼采《查拉图斯特拉如是说》

这几天看了这句话深有感触，见证过真正的黑暗，往往更加向往阳光的温暖。
