"Breathing the Spirit"

My youth is reading a book called Not A Fan by Kyle Idleman for our small groups on Sunday nights. Today, I was reading it during my personal finance class during some free time. It had a passage about "Breathing the Spirit." That passage really struck me, and I've decided to make a conscious effort to do this. Basically, what it is is this: When you feel yourself being angry, or selfish, or lustful, or greedy, etc. you exhale, exhaling these feelings, and in essence, the human-ness of you, or your Dark human nature. When you inhale, you inhale the Spirit, which fills all of you with it's Light. It's a really cool concept, and I'm trying to live that way.
