Scrying, also referred to as "seeing" or "peeping," is a practice rooted in divination and fortune-telling. It involves gazing into a medium, hoping to receive significant messages or visions that could offer personal guidance, prophecy, revelation, or inspiration. The practice lacks a definitive distinction from other forms of clairvoyance or divination but generally relies on visions within the chosen medium. Unlike augury, which interprets observable events, or divination, which follows standardized rituals, scrying's impressions arise within the medium itself.
The terminology and methods of scrying are diverse and lack a standardized structure. Practitioners coin terms such as "crystallomancy," "spheromancy," or "catoptromancy," naming practices based on the medium or technique employed. These practices have been reinvented throughout history, spanning cultures and regions. Scrying media encompass reflective, refractive, or luminescent surfaces like crystals, mirrors, water, fire, or smoke. Some practitioners even close their eyes, engaging in "eyelid scrying."
