You know, a few months ago, I made a terrible mistake. I realized something, and instead of crushing the thought the moment it came I... I let it hang on, and now I know it to be true. And I'm afraid it's stuck in my head forever. These are the best days of our lives. It's a terrible thing to know, but I know it.
Sadness gives depth. Happiness gives height. Sadness gives roots. Happiness gives branches. Happiness is like a tree going into the sky, and sadness is like the roots going down into the womb of the earth. Both are needed, and the higher a tree goes, the deeper it goes, simultaneously. The bigger the tree, the bigger will be its roots. In fact, it is always in proportion. That's its balance.
