If there is to be peace in the world, 

the nations must live in peace.

If there is to be peace among nations, 

the cities must not rise against each other.

If there is to be peace in the cities, 

neighbours must understand each other.

If there is to be peace among neighbours, 

there must be harmony in the home.

If there is to be peace in the home, 

we must each find our own heart.

-          Lao Tsu, China (sixth century BC)
