Think, for it's in you

Think of me as your guardian
think of me as your eye
leading you out
out of darkness
this madness
think of me and you'll see light
think of me and you may as well fight
think of me and you'll see
what is it like to be free
think of me when you're about to cry
or see a land that's so dry
think of me and you'll get your cue
think of me for I am in you.
