To fix hearts one must know one's own.

A heart is all that didn't get removed.

Once a thing is removed from your heart, a trace of it still remains.

To fall in love twice, with the same person, you need to grow another heart. That's all I do in my secret underground laboratory at night...

We are unknown to ourselves, we men of knowledge - and with good reason. We have never sought ourselves - how could it happen that we should ever find ourselves? It has rightly been said: "Where your treasure is, there will your heart be also"; our treasure is where the beehives of our knowledge are.

Always carry what is beautiful in your heart.
