Recently, I saw a 2010 recording of Lorn Hoff called “Zero.” In it, he talked about levels of simplicity.
I enjoyed the approach, so am sharing the principle here.
3: Diversity, our usual waking state, 3D material reality.
2: Duality, a key feature of Self Realization (Cosmic Consciousness). There is an inner wakefulness with a separate outer world.
1: Oneness, Unity, when the world is also recognized to be the same Self, they unite into one wholeness.
0: Brahman. With the Brahman shift we go beyond even the subtle dualities of existence into Nothing, the simplest. It is Zero.
That then sets the stage for ParaBrahman, purest Divinity. From ultimate simplicity, Divinity can return to itself.
