Without that, every conclusion you make and every meaning you derive will be a bit 'off', because you don't have something to properly contrast it against.
The trouble with trying to 'wake up' from spiritual unconsciousness, is that you're pretty much in the dark. Even though the truth is completely open and available, even if someone tells you what it is, you still won't be able to fully accept it at first. It's like, it's right in front of your face but you are hallucinating so much that you don't even recognize it.
Gradually you flail around in the dark trying to put pieces of the puzzle together, but it's like assembling a puzzle without the cardboard box cover to see what the finished picture is supposed to look like.
Luckily, because the thought system is consistent, as you start to get some pieces of it clear enough, those pieces allude to the content of other pieces. A piece shaped like 'this' sort of implies a piece shaped like 'that', and isn't compatible with one of those other pieces. So gradually as the picture forms, you get a better sense of what the whole picture looks like. As each new piece comes along, it becomes easier to 'predict' what it's going to say, and it builds upon this overall sense of knowing and certainty.
Also over time you get things deeper. You might've been exposed to the simple truth a long time ago but at the time you only kind of digested it on the surface, it didn't really occur to you how far reaching it was or what it really implied about your life. You gradually realize, holy shit, this is mind blowing.
So if anything, if there are tools to help you wake up, they might be tools which helps you to contrast whatever it is your experiencing against a kind of 'template' or definition of what is true and correct, so you can at least gauge a sense of whether you're on the right track or not.
For example, God is the truth, so you can quite easily say, "God does not create xyz because God is love and love wouldn't xyz, therefore... xyz is not real." Keep comparing it to the ideal of God as unconditional love and you can't go far wrong.
But for me, one really big truth which is hitting me strongly at the moment is that this entire physical world is not real. There is a truth beyond it which is much more true and correct. So this isn't just a matter of intellectually making sense but I'm starting to live it, and to relate to the world in a very different way because of this truth. I'm developing increased strength in God and conviction of His ways, and that means becoming more miraculous as well.
It just blows me away how much I'd fallen for the ego dream and all the different places that I went searching for truth here, finding none at all. Truly if we can depend solely on God for the Answer, we'll be very happy indeed.
