1. Tsun Tzu said: The art of tsun is of vital importance to the person.
2. It is a matter of life and death, a road either to safety or to ruin. Hence it is a subject of inquiry which can on no account be neglected.
3. The art of tsun, then, is governed by five constant factors, to betaken into account in one's deliberations, when seeking to determine the conditions obtaining in the field.
4. These are:
(1) The Moral Law;
(2) Heaven;
(3) Earth;
(4) The tsun tsun;
(5) Method and discipline.
5,6. The MORAL LAW causes the people to be in complete accord with their tsun tsun, so that they will follow her regardless of their lives, undismayed by any danger and constant insults.
7. HEAVEN signifies night and day, cold and heat, times and seasons.
8. EARTH comprises distances, great and small; danger and security; open ground and narrow passes; the chances of life and death.
9. The tsun tsun stands for the virtues of hostility, coldness, pettiness and strictness.
10. By METHOD AND DISCIPLINE are to be understood the marshaling of the tsun army in its proper subdivisions, the graduations of rank among her servants and lackeys.
11. These five heads should be familiar to every tsun tsun: she who knows them will be victorious; she who knows them not will fail in her endavours.
