Eventually, you'll (most likely) get bored of any occult library. We are creatures of novelty and need the prospect of endless new possibilities and never-ending mysteries in front of us, just to stay sane and functional. So the collection of life-handling recipes no matter how great and ancient, does not help. For example, imagine a world in which absolutely everything goes your way. You read all the books and became omniscient. As defacto a God of that reality, you would have total control over everything. Of course, you would have a blast for a while, enjoying everything you would find enjoyable. But sooner or later that ultimate satisfaction would fade away and you would find yourself entrapped by the "Universe of known things and phenomenons". No more uncertainty, no problems, no randomness and mystery, no more challenges. Just your total control over everything. Although what is described is every billionaire's wet dream, that is not a good place to be, because it hides a seed of madness and self-destruction.
