The real power of words

This is an excerpt from B.o.B's song from the Earth mixtape, titled "H.A.A.R.P Music"

"Whirl pool.
Earth moves, observe the truth of what words do.
Words do more than just hurt you.
Words alone fill up church pews
Words alone change the outcome,
Make you reconsider taking nurse school.
Words alone make you pay attention
To the problems that you never worked through.
Bird food for the mind."
