"The heart sends blood to every cell of the body, and in this way the cells are nourished. The same blood then flows back to the heart. If the flow is obstructed, the person will die. We need to learn this process of give and take from the heart. For the benefit of others, and also for ourselves, we should have the attitude of caring and sharing. We are all links in the chain of life. If one link is weakened, it will affect the strength of the whole chain."
