Traveller

I tossed a thought into the air
And sent it on it's way.
It travelled here, and travelled there,
Getting bigger every day.

It wondered on and on across
This wondrous world of ours.
Sometimes it stayed for several days
And sometimes merely hours.

It journeyed North and journeyed West
It journeyed South and East.
By this time it had grown so large
It was really quite a beast!

It went on it's way, and while it went
It picked up a billion others:
The replies of the people on it's route,
It's counterparts -  it's brothers!

This thought became a sentient thing.
Humanity's dreams unfurled.
And in it's wake, it seemed to leave
A calmer, gentler world.

It travels still, and will not stop
Until all nations find,
This single thought is ringing out
In every heart and mind.

What was it then, this random thought
I once chanced to release?
Not much at all, in the scheme of things.
Just a single syllable......Peace!
