When your study of Buddhism is through, you find you haven’t anything new. Enlightenment and delusion too never existed at the start. They’re ideas that you picked up, things your parents never taught. If you think the mind that attains enlightenment is “mine” your thoughts will wrestle, one with the other. These days I’m not bothering about getting enlightenment all the time, and the result is that I wake up in the morning feeling fine!
