First The Butterfly Effect
In simple terms this says that even the flapping of a butterfly wing makes a difference to weather patterns a world away.(Click here for a Wikipedia explanation in scientific terms!)
And then...
A quote from Lao Tzu (died 531BC):
“If there is to be peace in the world,
There must be peace in the nations.
If there is to be peace in the nations,
There must be peace in the cities.
If there is to be peace in the cities,
There must be peace between neighbors.
If there is to be peace between neighbors,
There must be peace in the home.
If there is to be peace in the home,
There must be peace in the heart.”
Maybe we can each make some "wing-flaps" of peace by seriously starting from the bottom of LaoTzu's quote and working our way up as far as we can.
