Strike Stone on Steel

STRIKE stone on steel,
Fire replies.
Strike men that feel,
The answer is in their eyes.
Powers that are willed to break
The spirit in limbs of pain,
See what spirit you wake!
Strike, and strike again!
You hammer sparks to a flame,
And the flame scorches your hand.
You have given the feeble an aim,
You have made the sick to stand.
You shape by stroke on stroke
Man mightier than he knew;
But the fire your hammer woke
Is a life that is death to you.
