Love is to care for someone. When you care, you feel the joy and pain of that person. Your feelings reside in the feelings of the other person. You can feel the flow of emotions. You are tuned in to your beloved.
When you have a beloved, or many, whatever the form of love is, there is no expectation in return. There is nothing to gain. In love, you become a pure giver. It's the only, natural way to act.
Giving a natural response to love !
