The Eleusinian Mysteries - Ἐλευσίνια Μυστήρια
The Eleusinian Mysteries operated on a precise, engineered technology of consciousness.
Seekers and Philosophers who were initiated, returned completely transformed and claimed profound life changing experiences.
What the system consisted of: Focused Dream incubation, deep philosophical study, a strict pure way of life and the use of specific plants and herbs.
There has been some debate in academia about what exactly the Kykeon, that initiates consumed, consisted of. However, through thorough research we can put together as many pieces of the ancient puzzles, that we can.
The kykeon was a psychedelic entheogen, carefully dosed by the hierophant to induce a controlled visionary state. The Greeks did not stumble into mystery; they engineered it. The psychedelic hypothesis is the only explanation consistent with the experiential reports, the agricultural context, and the pharmacological evidence:
Barley water, the known vehicle, mentioned in the Homeric Hymn to Demeter.
Ergot growing on the barley, processed to reduce toxicity. This is the Wasson-Ruck hypothesis, supported by ergot's presence on barley in the Rharian plain and the visionary effects of low-dose ergonovine.
Syrian Rue, that would intensify and prolong the ergot effect, reduce nausea, and direct the experience toward a more visionary, less toxic state. Rue was known in the ancient Mediterranean and used in Near Eastern ritual.
Pennyroyal (Mentha pulegium) - a common mint in Greece, known to induce mild psychoactive effects.
(This combination is the best proven synthesis)
The kykeon was a precisely calibrated entheogenic brew: barley water infected with ergot, potentiated by Syrian Rue, and possibly modified with pennyroyal. This is precise and careful Alchemy. The initiate drank, the hierophant guided, and the vision unfolded.
The hierophant revealed sacred objects (deiknymena); a cut ear of grain, a serpent, a phallus, a womb. The initiate saw "something" that transformed their view of death and afterlife.
>"I fasted, I drank the kykeon, ...I descended, I saw, I ascended, I became."
Initiates reported reduced fear of death, moral elevation, a sense of cosmic unity, and a permanent shift in identity.
The Mysteries were outlawed by the Christian emperor Theodosius I in 392 CE. The last hierophant was executed. The temple was destroyed.
The knowledge was buried, but fragments survived in Neoplatonism, Hermeticism, and Alchemy...

Apollonios of Tyana, after all his travels and experience with Alchemy/Medicine, had multiple encounters with the Mysteries and perhaps even tweaked the kykeon to ensure a more pure experience for initiates.
Given his pattern of refining traditions, it is plausible that Apollonios contributed to their evolution; emphasizing purity over animal sacrifice, ensuring the plant compounds and doses were perfect.
Throughout his life, Apollonios was known for rejecting the traditional animal sacrifices common in Greek rituals, including the Mysteries, often substituting them with incense.
So... Although the Mysteries are not solved, we can still learn a lot from them. The moral of the story here is not to do psychedelics... but to understand the intelligence of plants and the power of Dreams.
The Mysteries were an extremely well-built system crafted by Adepts, founded on ancient techniques, with the sole purpose of expanding human consciousness.
