What's in your head?

Because I heard the big crowd say
The words from pages of a broken book
My lost heart was led astray
From the path I should have took

The spells were vivid, loud, and clear
But still invisible from the light ahead
Fear was gone where courage stood
Strike the rivers, my devil said

I kept on searching for the cause
I wept out loud on my wee scars
But still I treaded the path to fight
I’d leap on darkness and make it cry

In the end my words were good
But the rivers flooded out the truth
My feet stayed firm on solid ground
My heart at peace with what I’ve found
