What is asked of us is simply to be a little bit willing to return to the Light of Truth. We don't have to have to be willing, ever, to have stuff ripped away before we are ready. Nor do we need to feel guilty when we are not ready or when we want to keep stuff. The truth is you WILL NOT let go of stuff when you are not ready because you can't let go without being genuinely willing and ready. Holy Spirit knows that and that it would be a complete waste of time to 'force' you.
At some point, if we are to wake up to truth, we need to be willing to entertain the possibility that what we think is true might not be - and that something we denied or thought wasn't true might well be the truth. We've denied God and we need to reverse that. But to reverse it we have to question where we've put our sense of value, and we've put it into many things that aren't really the truth.
So maybe we value music. Most people do. Or nice sunsets. Or videos of puppies and kittens. If you go do those things, in light of what the Course says, the ego will say "if you do this you're not doing the Course, so you are guilty". The ego positions itself as Holy Spirit's right-hand man as if bestowing the punishment that allegedly would come from Holy Spirit for your failure to comply. Holy Spirit did not appoint the ego to do this, and you're not guilty. Being mistaken doesn't mean you're guilty or deserving punishment.
At some point though you might be willing to get closer to God, and that will mean opening up to a greater truth. And once you expose yourself to the greater truth, you're not going to be ABLE to go backwards. It will also show you, in light, that what you thought was true or valuable, is really actually not AS valuable as the real truth. It's not as meaningful. ONLY when you are able to see through what you thought was important and recognize it for what it really is - an illusion, nothing of value, a decoy, or a ridiculous ego scenario, you will then be ready and willing to let go of it. Stepping into the truth IS letting go of it.
There is no force involved. There is no coercion. There is no pressure. There is no guilt for not being ready. WHEN you are truly ready, there won't be anyone standing there telling its about goddam time you sacrificed already. You will, and can, only let go of stuff, when you AGREE that the stuff you're letting go of is NOT of value to you, and that what you've chosen instead IS of value (God's truth). When you can see clearly in LIGHT, it is obvious what is true and what is false - what is valuable and what is valueless. Then there is no struggle and no fight. Nobody's ripping stuff from you, and you're not having to just go cold-turkey on stuff you still feel attached to before you're ready.
So yes you can keep all your stuff and your behaviors and your beliefs and all of it as long as you want. Guilt free. AND, even when you realize that this stuff is not truly worthy of the Son of God, that doesn't mean anyone's going to say "see told you so" or try to make you stop doing those things. You can still watch TV if you want, or walk the dog, or eat food. But the important difference then is that you do not NEED to and you don't believe it is reality.
At some point, when you are ready, you WILL look at every stone and turn it over and realize the gifts the ego was offering versus the gifts God is offering, and you will gladly choose God's gifts, and you will gladly and effortlessly let go of the ego's gifts. This includes all of the ego's laws. It includes all of the things you think you NEED and WANT, other than GOD alone, in order to survive and exist and be happy. That includes needing to eat food, drink liquid, sleep, breathe air, or be a body at all. You might still do these things for a while, but a MASTER does not need any dependence on anything besides God.
To summarize, there is no guilt or punishment coming for your 'sinful' behavior of enjoying chocolate cake or watching movies. But your dependence on these things as your source of truth might be keeping you away from something far more magnificent, and eventually you might decide to change your mind about what you want. And when you're ready to do that, Holy Spirit is right there ready to take the opportunity to gently guide you forwards to see for yourself what it is you've been denying.
Ultimately because you are denying God you are denying yourself/depriving yourself of everything God offers, which is an absolutely huge blessing that you've rejected. Why deny yourself such magnificence and joy? Jesus might at this point prod us - "ask yourself, do you want your little trinkets the ego has to offer, or do you want the love of God?" And since is it GOD that you stand to GAIN when you let go of things of lesser meaning, YOU CAN'T LOSE.
