Just to avoid confusion. I'm still only talking about supernatural explanations to phenomena. I'm not discussing ethics or emotional states.
I think it's the other way around. By turning inward and going with intuition you're making complex issues simple, which gets you further away from the truth. It may look like truth on the surface but isn't once you go digging.
The limit is always our own understanding. We'll never enter in theories that we've never heard of and theories we don't understand. I think it's impossible to leave intuition completely out of the decision making processes, but I do think it should be kept to a absolute minimum.
By turning inward in the way you suggest, I think your real goal is to find an answer that quells the searching your soul is doing. It has nothing to do with finding truth. If you've reached an answer that you are happy with, it only means just that. That you are happy.
Just like Red was saying. People might turn to the Bible because it is a constant in an ever changing world. It is constant because it is a gross simplification. It makes claims and assumptions it has no basis for doing. The fact that it is easy to understand doesn't add to the correctness. Even though it has plenty of answers I'm very doubtful any of them is the "truth".
