Miyamoto Musashi 宮本 武蔵 (c. 1584 – 13 June 1645) was a famous Japanese swordsman, believed to have been one of the most skilled swordsmen in history. He founded the Hyoho Niten Ichi-ryu, or Nito Ryu style of swordsmanship and wrote Go Rin No Sho (The Book of Five Rings) a classic work on strategy, tactics, and philosophy.
What is called the spirit of the void is where there is nothing. It is not included in man's knowledge. With your spirit settled, accumulate practice day by day, and hour by hour. Polish the twofold spirit heart and mind, and sharpen the twofold gaze perception and sight. When your spirit is not in the least clouded, when the clouds of bewilderment clear away, there is the true void.Until you realize the true Way, whether in life or in common sense, you may think that things are correct and in order. However, if we look at things objectively, from the viewpoint of laws of the world, we see various doctrines departing from the true Way. Know well this spirit, and with forthrightness as the foundation and the true spirit as the Way. Enact strategy broadly, correctly and openly. Then you will come to think of things in a wide sense and, taking the void as the Way, you will see the Way as void. In the void is virtue, and no evil. Wisdom has existence, principle has existence, the Way has existence, spirit is nothingness.
Some other schools have a liking for extra-long swords. From the point of view of my strategy these must be seen as weak schools. This is because they do not appreciate the principle of cutting the enemy by any means. Their preference is for the extra-long sword and, relying on the virtue of its length, they think to defeat the enemy from a distance. In this world it is said, "One inch gives the hand advantage", but these are the idle words of one who does not know strategy. It shows the inferior strategy of a weak spirit that men should be dependant on the length of their sword, fighting from a distance without the benefit of strategy.
