Second, I think when people say "it comes from the heart" I think they mean the mind. Your heart just pumps blood and keeps your body functioning. It's metaphorical in a sense. "Coming from your mind" would be the rational/irrational half of you. "Coming from the heart" is the emotional half of you. They work hand in hand, and the majority of times your "mind" wins out over your "heart".
So I guess I'm going with neither.
