We start with yin and yang in pure form. Yang is conventionally symbolized with a line (------). Yin is conventionally symbolized with a broken line (-- --). When these two blend perfectly they are replaced by T'ai Chi, which we symbolize as a circle (O).
If yin and yang do NOT blend perfectly, they either remain as is or else new forms arise. Yin and yang can be seen in these forms, therfore any symbol must show yin and yang. To symbolize these forms, and their biases (i.e. to yin, or to yang) we create 'digrams'. A digram shows two lines. Digrams of the 'pure' yin and pure yang are of the form:
-- -- ------
-- -- ------
Pure Yin Pure Yang.
The base line is the general bias. The line above it symbolizes a finer level of detail, the possible manifestation of an additional element. For the mutant forms we have two digrams:
------ -- --
-- -- ------
Mostly yin, Some yang Mostly yang, some yin.
These digrams symbolize the concept of bound. This term is used due to the visual nature of the digram, there is an obvious distinction of yang one side and yin the other.
To refine the distinctions we can add another line to the digrams, making them trigrams:
-- -- ------ ------ -- --
------ ------ -- -- -- --
-- -- -- -- ------ ------
However, these are not complete , since this refinement has brought out subtle additions, two of which emerge from the pure digrams and are associated with bond, and two of which emerge from the mixed digrams, and are associated with bind. The full set of trigrams (including symbols for pure yin and pure yang) is :
-- -- ------ -- -- ------ -- -- ------ -- -- ------
-- -- -- -- ------ ------ -- -- -- -- ------ ------
-- -- -- -- -- -- -- -- ------ ------ ------ ------
Pure Bond Bound Bind Bind Bound Bond Pure
Yin Yang
At this level of refinement we have both the pure elements and the mixed elements in apparent 'stable' states in that no further refining is required to bring out their generic nature.
Remembering that each line from the bottom up represents a bias, with the bottom line being of the highest value, we can make each line a representation of the percentage of yin or yang in the whole symbol:
Bottom Line = 55%, Middle Line = 30%, Top Line = 15%.
This gives us the bias values of:
-- -- ------ -- -- ------ -- -- ------ -- -- ------
-- -- -- -- ------ ------ -- -- -- -- ------ ------
-- -- -- -- -- -- -- -- ------ ------ ------ ------
Pure Bond Bound Bind Bind Bound Bond Pure
Yin Yang
100%yin 85%yin 70%yin 55%yin 55%yang 70%yang 85%yang 100%yang
0%yang 15%yang 30%yang 45%yang 45%yin 30%yin 15%yin 0%yin
The symbols we have here derived, are infact, equivalent to the trigrams used in the I Ching. In the I Ching, however, the concept of proportionality, where we move from the general to the specific, is often glossed over by the bias to the temporal nature of moving from a bottom line to a top line. As we will see this movement in three steps (six steps for a hexagram) implies that each line is of equal value. In the temporal sense they are, but in the structural sense they are not. We can, infact symbolize the temporal/structural relationships:
------ End -- Specific
------ Middle ---- Intemediate
------ Begin ------ General
Temporal form. Structural form.
The concept of wholeness has implied within it the concept of complete identity and therefore a balanced/unbiased state. From our discussion so far, we can associate wholeness, and therefore identity, with T'ai Chi. It follows that, since yin and yang are driven to unite back to T'ai Chi, this 'drive' manifests a seeking of balance, and therefore a seeking of identity.
As has been pointed out, pure yin is founded on feeling secure; trusting. Pure yang is founded on feeling powerful; confident. Developing, and thus uniting, trust and confidence, establishes identity; T'ai Chi.
As we have developed the mixing biases, we have found that the driving forces centre around establishing security/trust or confidence/power. Once established, the drives change to seeking the union of these two to reach T'ai Chi. Analysis of the mixing biases give us a sequence of development in two directions, T'ai Chi to bind and bind to T'ai Chi (See fig. 1.1).
(mutate)
T'ai Chi --> unmix --> yin/yang ---> mix ---> bond
(differentiate) ---> bound --> bind
<-- mix <-- yin/yang <--- unmix <--- bond
(integrate) <--- bound <-- bind
(REFINED) <------------------ RAW --------------------> (REFINED)
(MIXED) (PURE) (MIXED)
(SPIRITUAL) <-------------------------------------------> (MATERIAL)

Of interest is the association with the Qabalah - The Tree of Life, which is developed from Jewish mysticism:
((AIN SOPH)<---->KETHER<---------> BINAH/CHOKMAH <-->....
(Wu Chi) (T'ai Chi) (yin/yang)) <-->.......(MALKUTH)
(SPIRITUAL)<-------------------------------->(MATERIAL)

Success at each point on the path is dependent on the completion of the preceding point(s). If these steps are not totally completed then the refered 'abuses' may creep in.
Yin Path.
Trust-> betrayed
<- Forgiving -> Denied FEARLESS
--------------------------------------
FEAR
Securing -> Folly
Controlling <-> Corrupted
Yang Path
Confidence -> Arrogance
<- Resoluteness -> Excess FEARLESS
-------------------------------------
FEAR
Guiding -> Revolution
Invigorate <-> Faithless
All of the above deals with establishing wholeness, which implies Form. This implies that the yin/yang relationship is one of movement and therefore Process; an aspectual bias. However, if allowed to establish substance, then the yin/yang can lead to another level of 'wholeness'; not as 'pure' as the original but equivalent in the rhelm in which it is manifest.
In the traditional commentary called The Great Treatise the generation of the trigrams is explained thus:
"5. Therefore there is in the Changes the Great Primal Beginning. This generates the two primary forces. The two primary forces generate the four images. The four images generate the eight trigrams.The next link extends these concepts into the I Ching by extending the concept of refinement.
6. The eight trigrams determine good fortune and misfortune. Good fortune and misfortune create the great field of action." Chapter 11 of The Great Treatise in Wilhelm,R., pp 318-319
