It's no coincidence that LSD was (re)discovered in the midst of the horrors of WWII; it was a gift from above, a chance to reclaim the once-lost Eleusinian Mysteries and find our way back to Transcendence. Instead, the Shadow turned entheogens into a means of mere intoxication.
“[A]mong the many exceptional and divine things your Athens has produced and contributed to human life, nothing is better than those [Eleusinian] Mysteries. For by means of them we have been transformed from a rough and savage way of life to the state of humanity, and have been civilized. Just as they are called initiations, so in actual fact we have learned from them the fundamentals of life, and have grasped the basis not only for living with joy, but also for dying with a better hope.” — Cicero

“[H]ow can one describe, as other than oneself, that which, when one saw it, seemed to be one with oneself? This is no doubt why in the [Eleusinian] Mysteries we are forbidden to reveal them to the uninitiated.” — Plotinus
