How is voidness the absolute spirit of enlightenment?
Voidness or emptiness is the ultimate realization of cause and effect. It is the ultimate realization of the lack of inherent existence of all objects (unborn). Everything is a collection of aggregate parts that have come together through interdependent origination and will pass due to impermanence. Impermanence is also an unborn concept, it just happens. No-birth is a term used to explain the nature of Nirvana. Being in this state means that you no longer have attachment to impermanent things.
