So you're one of those 'follow your heart' types? That's dangerous territory. Is it your belief that your heart is a compass inside of you that will direct you to your own true north if you just have the courage to follow it? Believing that your heart is a true guide and that it will lead you to true happiness if you just have the courage to listen to it is dangerous.
I do not know how to respond because I do not know whether I'm one of those "follow your heart" persons or not, as I have no idea what you mean by "following your heart"?
I'm afraid you will have to explain it further.
Do you equate following you heart with...
1. Following your conscience?
2. Following your feelings?
3. Following the Spirit within me?
4. Following my understanding?
5. Following my physical urges?
6. Following my inherent desires?
6. Following the will I have for me and others?
7. Following temptation?
8. Following what I believe my needs are?
9. Following what I believe my wants are?
10. Following my interpretation of God's Words?
11. Following what I know God has revealed to me?
12. Following what I believe are God's promptings?
13. Following my emotions?
I could go on, but I think you get the point... Please be more specific?
