The Immortality Key : The Secret History of The Religion With No Name

The Immortality Key explores the theory that psychedelic substances were used in ancient Greek religious rituals—particularly the Eleusinian Mysteries—and may have influenced early Christian practices, including the Eucharist. Drawing on archaeology, ancient texts, and modern psychedelic research, Muraresku investigates whether visionary sacraments were a “lost technology” of spiritual experience later suppressed by the Church. The book presents provocative but debated evidence suggesting that altered states may have played a foundational role in Western religion. Introduction by Graham Hancock.
