Mystery schools are ancient educational institutions that focused on spiritual knowledge and personal transformation. They often taught esoteric wisdom, rituals, and practices aimed at helping individuals understand deeper truths about life and the universe. These schools were typically secretive, allowing only a select group of initiates to access their teachings. Many mystery schools, such as those associated with Ancient Egypt or Greece, emphasized the importance of inner experiences and self-discovery. They often used symbols, allegories, and initiatory rites to convey complex ideas. The teachings from these schools have influenced various spiritual traditions and philosophies throughout history.
