This path is indeed all about being honest with yourself.
Though your beliefs feel absolutely convincing, they are still beliefs. You don’t know what you believe for sure, and that’s why you believe it rather than know it.
Ask yourself whether you know whether what you believe is true or not. Be honest with yourself. If you’re really honest, you’ll find that you don’t know whether your beliefs are true or not and that you just kind of hope that they are. But if you’re a serious person willing to get serious about what’s going on here, in your life, in reality, belief just isn’t going to be enough anymore. You want real knowledge, Truth.
Be honest with yourself by being willing to go where it scares you the most. If there’s an area that you’re hesitant to think deeply about, out of fear that you might uncover something you don’t really want to uncover, go there specifically. Then keep going from there. This is about unwinding beliefs in layers, just start anywhere and the rest will all start to come undone as well.
