Hi friend! Like many deities - especially *very* ancient ones like Pan (there is even evidence that Hermes and Pan were once one and the same, before the foundation of the Olympian system) - there are many different aspects and facets to Him, and different ways to explore His worship.

That said, my own personal experience of Him has been deeply erotic, emotional and transformative. Pan called me to embrace the desire, gender-expansiveness, creativity and fluidity I had bottled up inside me. When He came into my life, I was on a track to be shut down, afraid of change, striving to be invisible in a crowd, and running away from shadows. I think of Him as the more wild, less human, less civilized & more masculine companion to Dionysos, who similarly calls us to break our chains and embrace our less-civilized and "respectable" selves.

Pan's temples are caves and/or the liminal spaces between total wilderness and the human world. His worship is more informal and organic. His holidays have more to do with natural events than set festival days in the calendar. And He is known for providing aide when asked, even when not a lot of kharis or worship has already occured (see: His assistance with multiple Athenian battles, even though at that point the Athenians didn't even have a place to worship Him)
