Also called crystal gazing, scrying is the magical practice of divining the past, present, or future by gazing into a usually reflective, translucent, or luminescent medium, such as crystal, mirror, water, or fire. The Cup of Jamshid, described in Persian mythology as a magical cup containing an elixir of immortality, is said to have revealed to the observer all the layers of the universe. Mirrors, meanwhile, have been said to reveal what to young women who gaze into them in a darkened room? Discuss
