That is true, but the word existence is of ambiguous meaning. A lot of confusion would be avoided by making a clear distinction between reality and existence. Existence pertains to space and time. Reality pertains to timeless and immaterial Truth.* Existence is not real, and the Real does not exist. But existence manifests the Real, God participates in the illusion; and insofar as we see the Real in the existent--"infinity in a grain of sand"--we may regard existence as 'relatively Real'. The dualism of Reality and existence, of the Absolute and manifestation, is inescapable, but at the same time it is transcended. For in the final analysis, only the Absolute is real, while existence is merely apparent. That which seems to be other than the Real, exists only within the mind of God.Dennis Mahar wrote:everything is void of inherent existence.
ineffable silence.
[* To elaborate: Because Reality is hierarchical rather than uniform, it may be divided into four levels or degrees: Beyond-Being (Dionysius), Pure Being, Intellect (Plotinus), and the Archetypes. Or, if you prefer, the Absolute, God, Spirit, and the Divine Names, respectively. These four levels constitute the Real; everything below this is existence.]
Inevitably. Dualism entails causation. Causation is not real. For it exists.you keep disclosing causes/conditions.
