A heart is made of flesh with blood veins. It has miracle muscles to keep the heart pulses pumping. How does the whole mechanism works if there is no battery or electric supply? From energy? But where?
Without heart, can the body works? The heart connected to other important part of the body to make the whole vessel moving. Same as human beings, every human has its important part to create the whole world a peaceful place. Imagine the absence of one of the organ. Does it function properly?
Two things : love and interconnecting. Love is the energy that combined all other human beings.
Love is not about you and me, but in the world at large. Handling a heart needed a great strength to understand.
