Should be, but it isn't. We live in the real world, not some Buddhist fantasy.
This is a very dangerous misconception. By equating enlightenment with moral perfection and an impossiblity of shadow, you set yourself up to be a great Zen Devil, full of much shadow. Because once your enlightenment happens, you'll still have a TON of shadow issues left unresolved, but your fantasy of perfection will force you to deny this fact and so you will suppress these shadow issues even deeper, doubling the size of your shadow and become a half-enlightened devil.
Even the greatest most enlightened masters have shadows and pathologies.
Don't be a fool. Nothing in this work is automatic.
You have no idea what imperfections Ramana Maharshi had. You just have a fantasy of him in your mind. It's easy to appear to have no imperfections when living one's entire life in a cave. The real test comes when you live an active life, where you have leadership obligations, duties, money, fame, sex, luxury, family, children, business, politics, and other things to deal with. When a hot girl with big tits comes and rubs them on you, let's see how long your enlightenment lasts.
