Explanes Zeus different names, but not why every Civilisation did perceived him differently. HPZM Sermon does explain it, should be added :
"Introduction: The Problem of Divine Appearance
The Gods don't hide. They aren't absent. They're always already present at every stratum of reality, all at once.
The real question isn't whether the Gods appear. It's why different people encounter them so differently. A farmer sees Zeus in the thunderstorm. A philosopher sees Zeus in the mathematical structure of the cosmos. A mystic sees Zeus in the dissolution of all structure whatsoever. All 3 are correct.
Plato's Divided Line (Republic 509d–511e) gives us the architecture for this. The Line isn't just an epistemological diagram. It's a map of how reality discloses itself, layer by layer.
Each segment corresponds to a different mode of being, and so a different mode of divine manifestation. The God doesn't change as the practitioner ascends. The medium of reception changes. The medium of reception is YOU.
What Zevism bolts onto this Platonic structure is the crucial insight that the practitioner's personal psychology determines which level they can access. Their cultural background, emotional wiring, training, spiritual maturity: all of it shapes the theophany. As you spiritually ascend, naturally you will climb this and this is exactly what the Gods want you to do.
The Gods meet you where you are. But where you are is decided by everything you've lived through, everything you've studied, everything you've felt. The theophany is always a collaboration between divine initiative and human readiness. In other words, you will be able to perceive the limit of your own understanding about the Eternal Gods. ..."
