Its got to be Dionysus every time, God of wine, madness, celebration and ecstasy. Born to a mortal woman, killed accidentally by his father Zeus and then reborn through him as a god. A permanent outsider as a newcomer, yet closer to humans than many of the gods having spent time walking the world as a human.
As to if i believe, ecstatic madness in celebration is something that i can relate to and that i think is something more than what we experience as individuals, if that counts....
