What does esoteric mean in the context of spirituality?

According to Osho, 'esoteric' in spirituality means ornate occult claims—seven bodies, fourteen planes, auras, and dead 'masters'—a hierarchy of fantasies with no real criterion. He dismisses it as sheer nonsense that seduces seekers away from direct, lived awareness. Spirituality, for him, is experiential and present, not a collection of secret maps or borrowed beliefs.
