According to Osho, the 'devil' who tempts Adam and Eve is not a real being but a supporting lie invented by priests, messiahs, and theologians to protect the more fundamental lie—God as an external creator. When you utter a basic untruth, you must fabricate further tales to shield it; the serpent-devil arises from this chain of human fiction and fear.
The snake devil is just a story people made up to cover another made-up story about God.
