Flowing Together Like a Song

In every relationship there are feelings between 'I' and 'I' which are innate and intrinsic to relationships. They exist naturally and only need to be understood..This innateness is called Harmony. Harmony has two meanings -  a complete agreement in behaviour, thinking and existential experience , and  complementariness in culture, civility, norms and orderliness. Moments of sharing, caring, loving and giving  are signs of a family that works. Where does the magic lie? Why do some families, no matter how large and unwieldy in numbers, flow together like a song, while others are gridlocked in conflicts and hatred or simply drift apart like a cloud of autumn leaves? Is a happy family a conscious creation or just an act of grace? Is there anything we can do to make our family life more fulfilling, more harmonious, more loving?
