After a time of decay comes the turning point. The powerful light that has been banished returns. There is movement, but it is not brought about by force. The old is discarded and the new is introduced. Both measures accord with the time; therefore no harm results. The movement is cyclic, and the course completes itself. |

The (first) appearance of anything (as a bud) is what we call a semblance; when it has received its complete form, we call it a definite thing —The I Ching. James Legge, tr

There are several ways to produce a hexagram, from the traditional to pragmatic.
Casting coins has been used for centuries as a way of consulting the I Ching and often favoured for it’s simplicity and ease. In contrast, the yarrow stalk method is widely considered more traditional, requiring dedication, time and careful elaboration of process. The coins may produce a result more quickly and directly (yang) while the yarrow stalks yield to time and can create contemplative focus (yin).
Quickest of all (thus far) is the general purpose computer, which can produce a hexagram seemingly instantaneously.

(i-ching-cast '3-coins)For the ultimate in computational pragmatism, you can produce a hexagram from a single 6-bit number.
(i-ching-cast '6-bit)The preferred method can be set or customized via the variable

In consulting an oracle the nature and source of chance,
synchronicity or randomness can be considered important aspects of the
process. Thus, this package can draw upon several source of randomness
including quantum (sampling quantum
fluctuations of the vacuum via ANU), atmospheric (atmospheric noise via random.org), or pseudo (pseudo-random numbers provided by the
local computing environment) Each method may be assessed for its
suitability and set as necessary.
(setq i-ching-randomness-source 'quantum)There are other significant methods which have not (yet) been implemented, in particular the “Ancient“ (Neo-Confucian reconstruction) and “Modified” methods of casting yarrow stalks described by Huang and some of the more idiosyncratic variants that have appeared during the 20th Century CE.
Consulting the oracle
Of course all divination is vain, nor is the method of the Yî less absurd than any other. — James Legge in The I Ching. Sacred Books of the East, vol. 16 (1899)
Consulting the I Ching as an oracle, in it’s most simple form involves asking a question, casting a hexagram and interpreting the hexagram and any possible changes to the hexagram.
You can query the I Ching with an invocation of
M-x i-ching-query
Or programmatically using any of the casting methods described previously.
(i-ching-query 'yarrow-stalks)Printing & displaying hexagrams
You can cast and insert a hexagram at the current point with
i-ching-insert-hexagram or insert a specific hexagram as
required with (i-ching-insert-hexagram 23)
Sometimes the hexagrams may not display correctly or be too small to read. The font and size can be adjusted as needed with minimal interference to how other characters are displayed….
(setq i-ching-hexagram-size 18
i-ching-hexagram-font "DejaVu Sans")If the glyphs don’t appear to change you may need to call
(i-ching-update-fontsize)
changing or moving lines
The 3-coins and yarrow-stalk methods
calculate values for the lines of the hexagram (6 or 9) and changing
lines (7 or 8) as described in the text and commentaries. These values
are represented internally as binary pairs which are used to produce a
single hexagram, or a hexagram and changing hexagram. The current
package does not provide commentary for individual lines or changing
lines, preferring the concise description of a hexagram (and potentially
the changing hexagram).
probabilities
The 3-coins and yarrow-stalk methods
produce slightly different probability distributions for casting a
hexagram as detailed in the following table (and discussed in more
detail in Probability
and the Yi Jing)
| Number | Yarrow stick probability | Three coin probability | Yin/Yang | Signification | Line |
|---|---|---|---|---|---|
| 6 | 1/16 | 2/16 | old yin | yin changing to yang | —x— |
| 7 | 5/16 (yang 8/16) | 6/16 (yang 8/16) | young yang | yang unchanging | ——– |
| 8 | 7/16 (yin 8/16) | 6/16 (yin 8/16) | young yin | yin unchanging | — — |
| 9 | 3/16 | 2/16 | old yang | yang changing to yin | —o— |

Pubic Domain sources
The translation from Chinese into English by James Legge, The Yî King (1882) as published in Sacred Books of the East, vol. XVI. 2nd edition (1899) is in the public domain and available via archive.org. It appears to be the only significant English translation that is currently in the public domain.
The German translation and commentary by Richard Wilhelm, I Ging Das Buch der Wandlungen (1924) is in the public domain and available via Projekt Gutenberg. Wilhelm’s translation from Chinese into German was translated into English as The I Ching or Book of Changes (1950) by Cary Baynes and should enter the public domain in 2047. Wilhelm’s translation has provided the basis for translation into several other European languages

Otherwise
The Gnostic Book of Changes provides a guide for “Studies in Crypto-Teleological Solipsism” by combining several translations, notes and commentaries, yet exists in a copyright grey-area. There is another emacs lisp version of the i-ching that can be found on the emacswiki which takes a slightly different approach and includes a few other methods, including calendrical, beads and the (unfortunately unimplemented) FUCKUP emulation mode as described in The Illuminatus Trology (there is also a programmatic replication of the Yarrow Stalk Method of I-Ching Divination available in javascript.)
