ARCANA

Think of the hidden or mystical secrets often associated with tarot cards or ancient rituals. This term can also refer to specialized knowledge known only to a select few.

"Esoteric knowledge" points to "arcana," a term for secret or mysterious wisdom often tied to occult traditions. The word itself comes from Latin arcanum, meaning "hidden thing," which fits the idea of knowledge not widely known. It’s a direct definition—no wordplay—just a precise match for something obscure and specialized. Think of tarot decks or ancient rituals when you hear it.
