Here's a thought: when studying Chi Kung, we learn that the body's "Shen", or spirit, is "stored" in the heart. Shen and heart energy are interchangeable concepts, as far as I know.
This a comment based on your question as to whether intuition came from the heart. It is a good question, but I still think this is a spiritual discussion. Perhaps I should re-frame my question in different language and try again, in the other forum.
But I'd love to hear more of your thoughts.
