The I-Ching is one of the oldest known forms of divination. It has been practiced in China for thousands of years. The name translates to "the Book of Changes" as this divination method foretells patterns of changes specific to that one moment in time. 

The method is simple: hold 6 coins of a similar size in your hand (5 of these coins should be the same type, 1 should be different, e.g. 5 pennies and 1 dime,) these are then tossed into the air and let to fall as they may. The coins are then aligned vertically in relation to the distance they are from the caster (i.e. the coin farthest away is at the top, the coin closest is at the bottom, the coins in the middle are aligned accordingly.) Based upon which coins are heads up and which are tails, a corresponding symbol, called a hexagram, is selected from the book. The differing coin's position enhances the meaning, adding another phrase to the definition of the hexagram.

This method is easy to learn, and all one really needs to practice is a copy of the I-Ching and a few coins, though, traditionally, yarrow stalks were used. However, this practice has fallen out of favor as it is more complicated.
