It's just a little thing
Only weighing 11 ounces or so
It has the power
To bring you to your knees
Or to lift you up and let you soar.
It rules us
Whether we want it to or not
We can give it away;
Or keep it close to us.
It holds our most precious
Feelings and memories
Many will say
That it's the head that rules
But it’s really the heart
Because wherever our heart is
Is where we are.

Linda Franklin
