Happy new year, everyone!
Increasingly, people at this time of year look back at predictions made by public psychics and mediums to see just how well they've done. Some are surprisingly accurate while others, well, let's say they aren't very good (are you listening, spirit of Criswell?).
One of the important skills of magicians is being able to perform divinations. Often magicians do this using the runes, Tarot, a crystal ball, or other such "assistants." As I've described in Modern Magick, the ability to perform divinations is important for working magick. After all, you logically would not want to perform a magickal act when the result might be negative or even harmful to yourself
