Divination is defined by Webster's New World Dictionary as:
There are an enormous variety of techniques for attempting to foretell the future.
Numerology: This is the practice of assigning a digit to each letter in a person's name, and deriving a series of numbers which have special significance to the person.
Palm reading: A person's future is foretold by observing the creases in their palm and shape of their fingers.
Runes: These are a group of from 16 to 31 (typically 26) letters of an ancient Northern European alphabet. The letters are inscribed on small rocks or pieces of paper or plastic. The runes are cast, and the future foretold from the runes that land inverted and not inverted, as well as from their location.
Scrying: This is a technique of producing visions of the future by gazing into a crystal ball, black mirror, bowl of water, hot coals from a fire, candle flame, bones, etc.
Tarot cards: This involves fortune telling through the use of a pack of 78 Tarot cards. The cards are shuffled; a few are dealt and laid in a specific formation (circle, cross, square, etc.). The cards are interpreted according to their intrinsic meaning, as modified by the significance of their location.
