Knock on the heart’s emotions and its gates will be widely opened, but nock on reason and doubt will come charging at you

I believe despite my doubts, belief gives me power reason takes away

Play with reason and doubt will close all the gates

You can deal with an emotion based on reason, but who can control an unreasonable emotion?

Emotion is created by a cause, whether that cause is factual or imaginary does not matter, as longer as the believer holds it as true.

Doubt is the first ray of illumination
