Love is not something you build. Is something you give yourself to. Everyone sells "images of love" in different forms just to have you investing in it, empty love everywhere, that is the issue. Love has become cheap, buy yourself some serotonin or dopamine boosters and you have your hands on that feeling. We are alienated from the real power and the source. Because like you say, people have figured out ways to use it and harness it's power, but in reality leaves everyone empty handed because the truth about Love and it's Power is that you have to be worthy of it. In your heart.
