Of the Long Sword

Mastery of any weapon or skill requires deep understanding of its properties and limitations, combined with calmness and precise execution—distinguishing quickness from speed and power from strength.

THE IDEA

OF THE LONG SWORD

In order to be able to fight well you must understand how to handle your weapons, whether they be swords or fists. Constant practice and becoming one with your sword are essential. Even if you should pick up a different weapon, by knowing the heart and nature of your own weapon you will be able to defeat men because of your sensitivity to the one. You must understand the limitations of what you are using before you can use them well. Think about this. It will become obvious in time.

Regardless of combat circumstances, you must always remain calm. Calmness is attained through meditation and belief in your own skills. It is not to be confused with egotistical technique, which generally fails under intense combat situations. Do not try to use techniques that do not fit the situation. An attack must be executed with quickness, not speed. Attack with power, not strength. There is a great difference between speed and quickness, power and strength. Think this through very carefully. It is the essence of strategy. You can use alternate devices as weapons, but their properties must be known or they might fail in a fight. A punch is a punch, a kick is a kick, and a strike is a strike. Do not confuse them with each other, as many often do when trying to use a kick technique where a punch is needed. A long punch is ineffective if used as a jab, and likewise, a jab is ineffective if used like a lunge punch. Understand the properties of the long sword and the short sword. Understand your weapons.

Always return your weapon along the same path it traveled out on. In this way you can use it again without having to relocate and rethink your attitude. The same applies to bringing the opposite hand back to the hip when you execute a punching strike. You must do this with authority and not in a haphazard manner. To fire a powerful punch requires that you fire straight and true while at the same time bringing the other hand back into a firing mode. Otherwise both movements will be weak.

When to use it

  • Improving performance in any martial art or combat sport by focusing on the essence of each technique rather than just repetition.

  • Enhancing decision-making in high-pressure environments (e.g., emergency response, public speaking) by maintaining calmness and choosing the right approach for the moment.

  • Training in any skill where progress depends on mastering one tool before moving to another (e.g., learning a musical instrument, coding language).

  • Developing a strategic mindset in competitive fields such as business, sales, or sports coaching, where understanding the 'properties' of your resources leads to superior execution.

FROM THEORY TO EVERYDAY LIFE

In practice

01

Applying the Principle to a New Sport

A tennis player at the net tries a forceful volley when a controlled block would keep the ball in play. Knowing the strengths and limits of each shot helps the player choose an appropriate response under pressure.

02

Business Negotiation

A negotiator who has mastered a specific tactic (the 'long sword') knows its strengths and weaknesses. When the situation calls for a different approach (the 'short sword'), they adapt rather than forcing the same technique. Quickness and power come from deep understanding, not mere speed or aggression.

✳

A MOMENT TO REFLECT

Put it to work.

  1. What is a 'weapon' (tool, skill, or strategy) you currently use? Do you fully understand its limitations and appropriate contexts?

  2. Can you recall a situation where you confused quickness with speed, or power with strength? How did that affect the outcome?

  3. In what area of your life could you benefit from returning your 'weapon' along the same path—i.e., executing a follow-through with authority and consistency?
