Well, Heart is the part of body only and its work is not more than doing lub-dub and control the health of the body. It is not concerned with nerve tree nor mind. While body is only tool to act with at the command of mind. And mind is weird if not controlled and attention on the matter. Mind is better with control of intellact by consciousness.
Thus I love to follow my consciousness.
I get what your saying without having to over analyze. So my answer would be, I would do what I have always done.....trust in the "heart" , the "soul" , the "mind" , the consiousness however you wish to say it. Tomato.... Tamato!
