Bonoloves to snippet Cohen. In facts someone has said , Bono wants to be Leonard Cohen.
In Oakland, we heard him insert Cohen's "There's a crack in everything; That's how the light gets in"
See 2:55ff in this clip:

Ring the bells that still can ring
Forget your perfect offering
There is a crack, a crack in everything
That's how the light gets in.

Anthem by Leonard Cohen

In another song you also say "There's a crack in everything, that's how the light gets in". It is not a very happy thought to believe that something will always have to break, to open a crack, in order to the light gets in...

Cohen: It is a happy thought if we enjoy the truth. There is always something that will have to break. Usually it is our personal pride. A Buddhist thinker said that disappointment is a great way to illumination. Other masters said: "from the broken debris of my heart I will erect an altar to the Lord".

The idea that there is a staircase of gold and marble, which leads to knowledge is seductive, but seems to me that the idea of something needing to get broken before we can learn anything is a more true idea. It is my experience, maybe you can escape it, but I doubt it. Unless the heart breaks, we will never know anything about love. As long as our objective universe doesn't collapse, we'll never know anything about the world.

We think that we know the mechanism, but only when it fails we understand how intricate and mysterious is the operation. So, it is true, "there's a crack in everything", all human activity is imperfect and unfinished. Only that way we can have the notion that there's something inside us that can only be located through disillusion, bad luck and defeat. Unfortunately, that seems to be the case.
