It's really simple. It's your belief system that blocks your recognition of God. So you say you can't live without a belief system. But what you don't realize is that your beliefs are your own. They are not universal, because they were created from your own experiences. Further, when you believe in a certain thing, you automatically don't believe in its counterpart. God is All. Thus you are setting up a system where you see separation, not the Unity that underlies all. The stronger someone holds beliefs, the more separation they see in themselves and the world, the more fear they feel, etc. Your beliefs are perceptions you hold, not Truth. You have to rise above the belief system to know Truth. And yes, you can operate in this world above a belief system --- that is sanity, that's what Jesus did --- in the world but not of it.
