It's the empty void at the center of it that troubles the mind. The duality of nothingness that lingers into doubt, that the void exists as either the absence of everything, or the potential for anything. This is the key metric of how we define our reality, yet something that escapes our ponder. Because deep down we're afraid of that absence, and what it means regarding permanence, or rather the impermanence of everything around us, and even ourselves.
