Chapter 1: THE GROUND BOOK
The Name Ichi Ryu Ni To (One school - two swords)
Warriors, both commanders and troopers, carry two swords at their belt. In olden times these were called the long sword and the sword; nowadays they are known as the sword and the companion sword. Let it suffice to say that in our land, whatever the reason, a warrior carries two swords at his belt. It is the Way of the warrior.
"Nito Ichi Ryu" shows the advantages of using both swords. The spear and the halberd are weapons which are carried out of doors. Students of the Ichi school Way of Strategy should train from the start with the sword and the long sword in either hand. This is a truth: when you sacrifice your life, you must make fullest use of your weaponry. It is false not to do so, and to die with a weapon yet undrawn.
If you hold a sword with both hands, it is difficult to wield it freely to left and right, so my method is to carry the sword in one hand. This does not apply to large weapons such as the spear or halberd, but swords and companion swords can be carried in one hand. It is encumbering to hold a sword in both hands when you are on horseback, when running on uneven roads, on swampy ground, muddy rice fields, stony ground, or in a crowd of people. To hold the long sword in both hands is not the true Way, for if you carry a bow or spear or other arms in your left hand you have only one hand free for the long sword. However, when it is difficult to cut an enemy down with one hand, you must use both hands. It is not difficult to wield a sword in one hand; the Way to learn this is to train with two long swords, one in each hand. It will seem difficult at first, but everything is difficult at first. Bows are difficult to draw, halberds are difficult to wield; as you become accustomed to the bow so your pull will become stronger. When you become used to wielding the long sword, you will gain the power of the Way and wield the sword well.
As I will explain in the second book, the Water Book, there is no fast way of wielding the long sword. The long sword should be wielded broadly and the companion sword closely. This is the first thing to realize.
According to this Ichi school, you can win with a long weapon, and yet you can also win with a short weapon. In short, the Way of the Ichi school is the spirit of winning, whatever the weapon and whatever its size.
It is better to use two swords rather than one when you are fighting a crowd, and especially if you want to take a prisoner.
These things cannot be explained in detail. From one thing, know ten thousand things. When you attain the Way of Strategy there will not be one thing you cannot see. You must study hard.
