There is a soul that lives in a body that's guided by a "Spirit". Sounds a bit strange a first, but when you think about it, the brain is not what always guides your decisions. Some people describe it as a "gut"feeling, how it resonates with them- on the inside. Others determine the level of "peace" they have around the topic, this, they use as a determining factor whether to move or stay put. Then another group describes the effect a thing has on their "heart". They often speak about a thing weighing or pulling at their emotions, I believe that tug for a believer, is the Holy Spirit trying to get our attention to lead us to a place behind what our minds can conceive.
