Prefnote
First become familiar with the very basic concepts of
consulting the Yi Jing before reading this simple survey. You should aready know
at least one method of casting a hexagram and the meaning of terms such as
"trigram," "changing line," and "static line." Nothing here is original -- all
credits go to the original authors; and apologies for any
misrepresentations.
1. Turtle shell / ox
bone
Crack a turtle shell with
heated rocks or sticks. Read the pattern of the
cracks.^{I}
2. Yarrow (milfoil
plant) sticks
Along with shell
and bone cracking, the manipulation of a group of yarrow stalks is the oldest
method of consulting the oracle. The procedures in use today are complex and
time-consuming^{II}; but they do serve to focus and clear the
questioner's mind. This is an example of how the yarrow method can work:
Of course, you may also count the number of stalks in the
remainder pile -- but that goes by a different chart.^{III}
You have now determined the first (bottom) line of your six-line hexagram. Now
gather all 49 stalks together and:
Repeat steps 1-4 all over again for each of the five remaining lines.
Repeat five times to determine the remaining five lines of the hexagram. Multiple changing lines are possible (more so than with the yarrow stick method). Some schools provide systems for limiting the number of changing lines recognized when using the yarrow and three-coin methods.^{V}
4. Four
coins
The tossing of 3 coins and
the dividing of yarrow stalks do not have the same statistical probabilities in
producing lines. In the belief that the yarrow method is more reliable and/or
more ancient, some 4-coin methods have been developed that duplicate the
probabilities of yarrow divination.[VI] For example:
6. Six coins
[Sorrell/Sorrell]
Toss 5 pennies
and 1 dime with eyes closed. (Six pennies, one of which is visually different,
would also be acceptable.) Use hands to form coins into a column representing
the hexagram. Open eyes and read:
7. Six
sticks
Six four-sided sticks are
used. Yin and yang lines -- static and changing -- are marked on the four faces
of each stick. The distribution of the line markings varies. Sometimes each
stick is marked with all four types of lines. Cast the sticks and form them into
the shape of a hexagram. Even more that the 3-coin method, this increases the
probability of receiving changing lines.^{VII}
8. Sixty-four
sticks
Place 64 numbered bamboo
slips into a wooden or bamboo cup. Shake the cup until one or two slips slip
out. Read the corresponding hexagram(s).^{IX}
9. Yarn
sticks
Pick a group of yarn
sticks at random from a container of less than 50 sticks. This determines your
lower trigram. Repeat the process for the upper trigram. There are no changing
lines.^{X}
Heaven: 1 | 09 | 17 | 25 | 33 | 41 sticks |
Lake: 2 | 10 | 18 | 26 | 34 | 42 sticks |
Fire: 3 | 11 | 19 | 27 | 35 | 43 sticks |
Thunder: 4 | 12 | 20 | 28 | 36 | 44 sticks |
Wind: 5 | 13 | 21 | 29 | 37 | 45 sticks |
Water: 6 | 14 | 22 | 30 | 38 | 46 sticks |
Mountain: 7 | 15 | 23 | 31 | 39 | 47 sticks |
Earth: 8 | 16 | 24 | 32 | 40 | 48 sticks |
11. Six questions
[Lofting]
The inquirer is asked
two sets of three questions about his inquiry. Based on the answers, a hexagram
is built. The first three questions deal with the inquirer’s ("my") assessment
of the situation:
12. Gender method
[Perrottet]
In The Visual I
Ching,^{XII}the inquirer takes eight cards, each displaying a
visual image of a trigram, and holds them or places them face-down. He then
mixes them up, chooses one, and notes it. This is repeated five more times.
Trigrams associated with male members of the family yield yang lines, and vice
versa:
Heaven | father | yang line |
Lake | youngest daughter | yin line |
Fire | middle daughter | yin line |
Thunder | eldest son | yang line |
Wind | eldest daughter | yin line |
Water | middle son | yang line |
Mountain | youngest son | yang line |
Earth | mother | yin line |
13. Eight gems and a
die [A. Huang]
Place eight
different stones into a bag (predetermining which stones represent each of the 8
trigrams). Pick a stone; this is your lower trigam. Place it back in the bag.
Pick a stone; this is your upper trigram. Roll the die. The number on the die is
the number of the hexagram's changing line.^{XIII}
14. Sixteen cards
and a die [A. Huang]
On 8 red
cards and 8 blue cards mark the symbols of the 8 trigrams. Shuffle the cards
upside down and choose one blue card for the lower trigram and one red card for
the upper trigram. Roll a die to determine the number of the changing
line.
15. Cassia Tora
seeds. [Ni]
Six "pinches" of
small seeds or grains of rice are placed on a plain sheet of paper, representing
the 6 lines of a hexagram. If a cluster of seeds contains an even number of
seeds, the line is yin; if odd, yang. One additional pinch of seeds is dropped
and counted. This determines which line is the one on which to focus. If the
number is greater than 6, 6 is subtracted and the remainder is the focus line.
("Focus line" is my term to indicate no additional hexagram is to be
consulted.)^{XIV}
16.
Situation-related trigrams [Shao Yong, c. 1066]
In this method, aspects of a particular situation are used to
determine the trigrams which relate to it. The relationships of the trigrams'
imagery are then examined to determine a reading.^{XV} "Aspects"
include such things as:
18. And finally,
just open the book at random and read it.

Footnotes:
I A small hole is drilled on one side of the shell. The heat source is applied there and the cracks form on the other side. One "cracking" requires approximately 1.5 square inches of shell. This method was used with turtle shells and with bones -- usually the shoulder blades -- of oxen.
II The methods in use today are from 1,000 to 3,000 years old. The exact date is a subject of much scholarly debate. Most methods today are based on a description in a collection of Confucian-style commentaries on the Yi Jing known as the Ten Wings (in particular, see Chapter 9 of the Great Treatise/Appended Judements of the Ten Wings). The language in all the Ten Wings is full of imagery. Here is just one passage about the yarrows:
The number of the Great Expansion is fifty,On the web, a very clear yarrow description is detailed at http://www.power-press.com/yarrow.html (Power Press's wu wei site). It even has pictures!
Of which forty-nine are used.
Divide them into two, symbolizing the two primary forces.
Suspend one, symbolizing the three supreme powers.
Manipulate by four, symbolizing the four seasons.
Return the remainder, symbolizing the intercalary month.
In five years there is another intercalation.
Afterward the process is repeated.Therefore four operations produce a change,
And eighteen changes yield a gua. (--Translation A. Huang)
III Here is the basic chart when counting "leftovers:"
27 = An "old" (changing) yin (broken) lineThere are also symbolism-based formulas that convert these numbers into the tradtional codes 6, 7, 8, and 9 (respectively). Wilhelm/Baynes is a good resource for that.
21 = A "young" (static) yang (solid) line
17 = A young yin line
13 = An old yang line
IV Diana ffarington Hook's The I Ching and You (0-7100-7381) includes one description of the symbolism involved in the 3-coin method. (Thanks to Isabeau Vollhardt for the quotation):
...where there is a mixture of heads and tails, that is 7 or 8 in a single throw, there is a more or less balanced condition, part yang and part yin, and the answer is a yang or yin line. However, when all three coins fall the same way up, that is three heads (9) or three tails (6), the situation is unbalanced, being either too yang, or too yin. These lines are then in an important state of change or movement, changing because of the excessive imbalance.V For details, see Hacker or Whincup (ISBN's below).
VI There are multiple methods that use four coins and exactly
duplicate the probabilities of using yarrow stalks. Edward Hacker presents
his in his book The I Ching Handbook (ISBN 0-912111-36-4). Stuart
Anderson, whose description of "Alternate Coin Method #2" appears above, has
laid out the mathematics (along with another 4-coin method) in his article at
Charlie Higgins YJ Mensionization site http://www.mension.com/probab1.htm
. A third 4-coin method was mentioned by Al Franken. In this method,
four coins are tossed at once; however two of these are pre-designated to work
together and count as only one coin. Again, "heads" = 3, and "tails" =
2. However, if either of the predesignated pair is a "heads," they both
count as one "heads." The resulting hexagram lines are then the same as in
the 3-coin method where 6 = changing yin, etc. Al Franken pointed out he
prefers a 'statistically correct' 4-coin method because hexagrams obtained by
yarrow or 4-coin methods are less pessimistic than those of the traditional
3-coin method. Ralph Abraham ( http://www.ralph-abraham.org/ )
demonstrates mathematically why yarrow probabilities are more "optimistic" than
those of the coin oracle:
[In regard to the probabilities of obtaining a particular type of line using the yarrow method:] All this is explained in detail in Wilhelm, pp. 721-722. In summary:
He goes on to give the coin probabilities:6 -x- old yin 1/16This is radically different from the coin oracle, and this is just one reason for preferring the yarrow method.
7 --- young yang 5/16
8 - - young yin 7/16
9 -o- old yang 3/16In practice, an experienced hand will not achieve these probabilities, for the reason described above. In avoiding the very unequal divisions, a small advantage is gained to the remainder 8 and its score 2, and so the expectation of a 6 line, old yin, will be a bit larger than 1/16. This effect is included in our simulation by the use of a chaotic attractor to arrange the heap. By a series of experiments, you may choose a heap algorithm to match your own hand.
Line probabilities in the first hexagram
Casting a hyperhexagram with 18 divisions of yarrow determines two hexagrams. A yang line in the first hexagram results from either a young yang or an old yang hyperline in the hyperhexagram. Thus the probability of an initial yang line is the sum of the probabilities of old yang (3/16) and young yang (5/16) or 8/16: 50%.The chances of an initial yin line are similarly the sum of old yin (1/16) plus young yin (7/16), or 8/16: 50%. Initially, yang and yin are equiprobable. This is the same as the coin oracle, in which initial yin and yang are also balanced 50-50.
Probabilities for changing lines
The chances of a changing yarrow hyperline are (1/16) for old yin, plus (3/16) for old yang, or 4/16: 25%. Again, this is the same as in the coin oracle.Line probabilities in the second hexagram
In the second hexagram, a yin line results from either an original young yin (7/16) or an old yang (3/16) or 10/16 = 5/8. Similarly, a yang line results from either an initial young yang (5/16) or an old yin (1/16) pr 6/16 = 3/8. Here we have a significant difference between the yarrow-stalk oracle and the coin oracle.With the YSO, final yin is 5/3 times more likely than yang. This is the reason for thinking that the coin oracle has contributed to world problems.
In each coin toss there is one chance in two or probability of 1/2 of obtaining a head or a tail. As three coin tosses determine a line, it is easy to compute the probabilities of the four lines:
After casting a hyperhexagram with six tosses of three coins, a yang line in the first hexagram results from either a young yang or an old yang hyperline. Thus the probability of a yang line is the sum of the probabilities of old yang (1/8) and young yang (3/8) or 4/8, 50%. The chances of a yin line are likewise 50%. This is an equal opportunity system.6 -x- old yin 1/8
7 --- young yang 3/8
8 - - young yin 3/8
9 -o- old yang 1/8The chances that a hyperline will be changing, old yang or old yin, is (1/4 + 1/4) or 25%.
