The main difference in Sun Tzu's version is that
the natural forces of "water" and "fire" (from the "Before
Heaven" Bagua) are replaced with the "commander" and "methods"
(see diagrams). Layers of connections often shown around the Bagua
are how ancient Chinese scientists understood the deep
connections in the natural order, illustrated in the first two charts
above.
For Sun Tzu, fire and water were opposites, but
not complementary opposites because one did not generate the
other. For Sun Tzu, the idea of complementary opposites was the key to
understanding all systems. Systems existed as a balance of complementary
opposites. While fire is associated with methods, it is more accurate to
say that it is associated with positioning, the skill that connects
methods with the earth. Fire doesn't create metal directly, but it
creates metal by smelting rock (earth). Metal is symbolic of leadership,
but more precisely, knowledge. Metal creates fire by striking it against
a rock (earth), but the key is knowing the right type of rock. As you can
see, this system is quite precise and its relationships are
comprehensive, but the only reason to explore them all is to better
understand the original text, not Sun Tzu's system itself.
Though Sun Tzu almost certainly knew of some
form of the Bagua in its "Before Heaven" form, he does not use
all its elements as any
direct basis for his work. The elements are used symbolically, but
some are very important while others are relatively minor. Thunder, for
example, is seldom used, and then symbolically to emphasize the obvious
knowledge used by vision (known as aim). Water is symbolic of change,
but lakes are symbols for hidden or secret changes. Woods are a minor
symbol, used as a characteristic of ground, primarily representing
stability.
The diagrams that reflect Sun Tzu's model are used in our live seminars and
seminar videos, and are explained in more detail in our
Amazing Secrets book and seminars. Sun Tzu's method of using diagrams defines
him as a
pragmatist rather than a philosopher. He was more interested in the real
workings of the world than any "ideal" patterns behind it.
