Mind, Body, Soul
The premier classic of the science of strategy in conflict. The healing arts and martial arts are parallel in several senses: in recognizing that the less needed is the better, in the sense that both involve stategy in dealing with disharmony, and in the sense that both knowledge of the problem is "key" to the solution.
In Sun Tzu's philosophy, the peak efficiency of knowledge and stategy is to make conflict altogether unnecessary. There are grades of martial arts: the superior militarist foils enemy plots; next best is to ruin their alliances, next is to attack their armed forces; worst is to beseige their cities.
The ideal strategy is whereby one could win without fighting, accomplish the most by doing the least, that bears the characteristic stamp of Taoism-the ancient tradition of knowledge that fostered the healing arts and martial arts in China, (The Art of War, Sun Tzu, translated by Thomas Cleary, (1991)).
