The Sun Tzu School Ping-fa Directive. Be strong and continually aware. Manage your strength and that of others. When essential, engage on your terms. Be observant, adaptive, and subtle. Do not lose control. Act decisively. Conclude quickly. Don't Fight!

The Sun Tzu School (which wrote the Art of War) surely never imagined that their antiwar, pro-empire treatise would become known and accepted after the fall of the first empire as a text on military tactics. Likewise, they would have been surprised to see the Ping-fa military metaphor—an inspired teaching device—come to be seen as the message and not the medium.
