The I-Ching, or "Book of Changes," is an ancient Chinese oracle book that deals with philosophy and divination. Inquiring souls pose a question to the oracle in the hopes of receiving an answer. Simply put, the tossing of coins helps you form a group of lines (trigrams and hexagrams) that lead to a better understanding of one's present and future situation. Trigrams are a series of three lines (either solid or broken lines) while hexagrams are comprised of six. Once a pattern of lines is formed, the oracle book is consulted for answers to the question posed to it.

Dating to the Chou dynasty (1100 BC), the I-Ching was heavily influenced by Confucius, who used his considerable scholarly abilities to help form the Ten Wings -- the commentary that offers explanations of the hexagrams. Later scholars melded principles of astronomy and astrology (the five elements and the twelve zodiacal characters) into the I-Ching. Known as "The Book of Changes" to Westerners, the resulting oracle book is a comprehensive text covering ideas, images and natural laws that can provide answers to specific questions.

In the I-Ching, the hexagrams used for the purpose of obtaining answers are formed by the tossing of coins. Using three like coins (say, quarters), each side is arbitrarily pegged as either yin or yang. For example, "heads" might be yin while "tails" is yang. In this scenario, "heads" would be assigned a value of three while "tails" counts as two. Center yourself, be calm and ask a specific question of the oracle. Follow this by shaking and then tossing the coins. As they land yin or yang, total the value of the three coins and jot down that number (the only possible sums are six, seven, eight or nine). Toss the coins a total of six times and note each corresponding value.
