One thing I have learned over the years:
A gentle heart is ripped open every time a loved one leaves. But like bones broken or skin cut, it heals stronger so that with the next love it feels, it can beat harder and fiercer. You see, a heart is without memory of its pain; it feels only in the present its greater strength and courage, not knowing that it will be ripped open again, nor that it ever was before. Because of this, the heart does not hesitate to love... It forgets the risk and remembers only the gain. Maybe the mind should be the same?
