To Only Know

Another old poem. Been a long while, can't remember the background for this...

To stare at the sun
To gaze upon it as it sinks down
Beneath the stretched sea
To smile at the end of the day
Then breathe the crisp air
Of a new day soon to begin
To only know that what you think
Can only be something
That can only be believed
Its all something that that
Can only be known,
Can only be understood,
When the heart you have
Is in another's hands.
