Is It My Brain Or Nafs?
This is the conflict of evil and good for which we are created to choose the good and thus be rewarded. The evil and good are in our Nafs, and then the brain works accordingly. Rousing of such feelings never stops but fades away with the passage of time if we work on it consistently. To end these feelings is not possible nor required. All we have to do is to make a decision is favour of piety and good.
