How is Hester's heart described? What does this description mean? How is this to affect how one would understand Hester's thoughts and actions?

I'm not sure exactly where you mean. Hester's heart is mentioned in many places. Can you give me a specific chapter?

ch 5

That's one of the reasons I had trouble answering this question is because I didn't really know which chapter to find this answer in since the enitre book is about a passion crime against the word of God...
