Therefore measure in terms of five things, use these assessments to make comparisons, and thus find out what the conditions are. The five things are the way, the weather, the terrain, the leadership, and discipline. The Way means inducing the people to have the same aim as the leadership, so that they will share death and share life, without fear of danger. The weather means the seasons. The terrain is to be assessed in terms of distance, difficulty or ease of travel, dimension, and safety.
Leadership is a matter of intelligence, trustworthiness, humaneness, courage, and sternness.
Discipline means organization, chain of command, and logistics. Every general has heard of these five things. Those who know them prevail, those who do not know them do not prevail. Therefore, use these assessments for comparison, to find out what the conditions are. This is how you can know who will win.
