Well,

this whole idea is, that once you understand that love is understanding, the title makes a lot of sense. It is probably more for those who already know this. You can’t understand what it says until you know what is behind it. If you replace the words, it would be like this:,,I got to understand love. And if you do not understand what I just said, you do not understand love. ”

The message is, that love is understanding, and because of how the sentence is made, once we know how is it meant, it shows its power. (Or just me?)
