This MPX entry clarifies the structural distinction between Buddhist articulations of emptiness and luminosity — especially in Dzogchen, rangtong / shentong discourse — and the Zenetist registers of ⚫ Aion, ♾ Khaon, L₀ Bifurcal Coherence, ⦿ Kaion, and 🕳️ Zenon.Emptiness is read as Aion‑ward negation: a motion of subtraction that removes reification but does not cross the bifurcal limit. Luminosity is read as Khaonic / Theonic expression: clarity, awakened presence, and spontaneous manifestation within awareness-bearing structure. Their inseparability in refined Buddhist nondualism is placed at L₀ Bifurcal Coherence or, at its convergence limit, Kaion—both profound but still structural.Zenon is distinguished from all of these. Zenon is not emptiness, luminosity, awareness, nonconceptual cognition, or the reconciliation of the pair. It is the trans‑structural allowance by which polarity, awareness, emptiness, luminosity, and the entire field of discernibility become possible.The entry also contrasts Buddhist non‑essentialism with Zenetism’s non‑egoic essence: an identity-bearing principle spanning L₅, L₀, and rare saturation into Zenon, without collapsing into substantialism or dissolving into undifferentiated sameness.The result is a respectful comparative placement: Buddhist nondualism is structurally deep, approaching the bifurcal limit, but remains distinct from Zenon. The distinction is non‑fusional and preserves the integrity of both systems.
