It is as absurd to say that a man can't love one woman all the time as it is to say that a violinist needs several violins to play the same piece of music.
We believe we are hurt when we don't receive love. But that is not what hurts us. Our pain comes when we do not give love. We were born to love. You might say that we are divinely created love machines. We function most powerfully when we are giving love. The world has led us to believe that our wellbeing is dependent on other people loving us. But this is kind of upside down thinking that has caused so many of our problems. The truth is our well being is dependent on our giving love. It is not about what comes back; it is about what goes out!
