Give until it hurts

"It is very important for us to realize that love, to be true, has to hurt. I must be willing to give whatever it takes not to harm other people, and, in fact, to do good to them. This requires that I be willing to give until it hurts. Otherwise there is no true love in me and I bring injustice, not peace, to those around me. "
