4. That the impact of your army may be like a grindstone
dashed against an egg--this is effected by the science
of weak points and strong.

5. In all fighting, the direct method may be used
for joining battle, but indirect methods will be needed
in order to secure victory.

6. Indirect tactics, efficiently applied, are inexhaustible
as Heaven and Earth, unending as the flow of rivers and streams;
like the sun and moon, they end but to begin anew;
like the four seasons, they pass away to return once more.

7. There are not more than five musical notes,
yet the combinations of these five give rise to more
melodies than can ever be heard.

8. There are not more than five primary colors
(blue, yellow, red, white, and black), yet in combination
they produce more hues than can ever been seen.

Nice job!

9. There are not more than five cardinal tastes
(sour, acrid, salt, sweet, bitter), yet combinations
of them yield more flavors than can ever be tasted.

10. In battle, there are not more than two methods
of attack--the direct and the indirect; yet these two
in combination give rise to an endless series of maneuvers.

11. The direct and the indirect lead on to each other in turn.
It is like moving in a circle--you never come to an end.
Who can exhaust the possibilities of their combination?

12. The onset of troops is like the rush of a torrent
which will even roll stones along in its course.
