Oneness is when we see that the root cause of all creation goes back to one thing, call it “an explosion in space”, “energy”, or “God”. It is all-pervading, and as this divinity, I am all-pervading. There is no distinction, division, nor any difference. Oneness is also in the interconnectivity of everything around us. We are linked, affected by and dependent on everything in creation. But we often fail to see this logic for our ego, or the “i”, asserts differences and individuality. So, surrender the ego.
