"In The Immortality Key, Muraresku explores a little-known connection between the best-kept secret in Ancient Greece and Christianity. This is the real story of the most famous human being who ever lived (Jesus) and the biggest religion the world has ever known.... Before Jerusalem, before Rome, before Mecca, there was Eleusis: the spiritual capital of the ancient world. It promised immortality to Plato and the rest of Athens's greatest minds with a very simple formula: drink this potion, see God. Shrouded in secrecy for millennia, the Ancient Greek sacrament was buried when the newly Christianized Roman Empire obliterated Eleusis in the fourth century AD. Renegade scholars in the 1970s claimed the Greek potion was psychedelic, just like the original Christian Eucharist that replaced it. In recent years, vindication for the disgraced theory has been quietly mounting in the laboratory. The rapidly growing field of archaeological chemistry has proven the ancient use of visionary drugs. And with a single dose of psilocybin, the psycho-pharmacologists at Johns Hopkins and NYU are now turning self-proclaimed atheists into instant believers.... Armed with key documents never before translated into English, convincing analysis, and a captivating spirit of quest, Muraresku mines science, classical literature, biblical scholarship and art to deliver the hidden key to eternal life, bringing us to what clinical psychologist William Richards calls "the edge of an awesomely vast frontier."" --Provided by publisher.
