The Book of Five Rings

Chapter 4: THE WIND BOOK

You must train diligently. I have tried to record an outline of the strategy of other schools in the above nine sections. I could now continue by giving a specific account of these schools one by one, from the "gate" to the "interior", but I have intentionally not named the schools or their main points. The reason for this is that different branches of schools give different interpretations of the doctrines. In as much as men's opinions differ, so there must be differing ideas on the same matter. Thus no one man's conception is valid for any school.

I have shown the general tendencies of other schools on nine points. If we look at them from an honest viewpoint, we see that people always tend to like long swords or short swords, and become concerned with strength in both large and small matters. You can see why I do not deal with the "gates" of other schools.

In my Ichi school of the long sword there is neither gate nor interior. There is no inner meaning in sword attitudes. You must simply keep your spirit true to realize the virtue of strategy.
