When man is serene, the pulse of the heart flows and connects, just as pearls are joined together or like a string of red jade, then one can talk about a healthy heart. – The Yellow Emperor’s Canon of Internal Medicine, 2500 B.C.
There is in every human heart Some not completely barren part, Where seeds of truth and love might grow, And flowers of generous virtue flow; To plant, to watch, to water there, This be our duty, be our care. – Sir John Bowring
