At the end of the Earth Book, Miyamoto lists nine principles by saying,, He who wishes to undertake to study my Hyoho should be aware of the following:

First: Do not harbour sinister designs. This means that one must think correctly from a righteous viewpoint.

Second: The way is training. Meaning, he implies that one must train in everything and accomplish it in addition to the way of hyoho. Miyamoto calls one thousand day practice Tan (hardening). Ten thousand days Ren (practice). In other words, one thousand days refers to three years and ten thousand to thirty. The intention of Miyamoto is to explain that one must continue to seek the way.



Third: Cultivate a wide range of interests in the arts. Miyamoto emphasises not to limit ones learning only to Kenjutsu, but to devote oneself whole heartedly to everything. The ten skills and ten arts. Then one can definitely find the benefits of hyoho and can develop oneself.

Fourth: Be knowledgeable in a variety of occupations. He emphasises getting acquainted with as many occupations and skills as possible, and learn the thinking of many people who have work in them.

Fifth: Be discreet with regard to ones financial dealings. Miyamoto is advising one to know the difference between loss and gain in worldly matters.

Sixth: Nurture the ability to perceive the truth in all matters. It is important to build up an intuitive judgement and understand true values.

Seventh: Perceive that which cannot be seen with the eye. This means to strive to develop intuitive judgement and a mind can freely control ones body.

Eighth: Do not be negligent, even in trifling matters. This means to pay attention, even to small matters. Keep them in mind all the time, so as to avoid unexpected failure.

Ninth: Do not engage in useless activity. Do not argue about useless things. Concentrate on your own duties and give up other things.


As a result of these nine principles which Miyamoto presents, one can live in the world of Hyoho.

Miyamoto describing the fundamental principles of the Hyoho as, profitable measures are not limited to the standard techniques of swordsmanship alone. He clarifies that the utmost world of master swordsmanship is to establish oneself, to guide others, to gain benefits, and to make peace with others.



Comparing the nine principles with hashodo (the eightfold path), Shakamuni taught Buddhists the way of aesthetic training. Both teach the same concepts. In the words of Bodhisatta, in order to save people, one must serve an infinite number of Buddhas, understand their thinking, and acquire them to oneself.

Miyamoto explains the nine principles with his own words. Musashi the swordsman, mastered the utmost spiritual awakening without using a sword. He developed himself and reached the first stages of this world. Miyamoto Musashi the hyohoist, describes himself in the section Iwao no Mi (The body of a Massive rock) at the end of the Fire Book.





When you have mastered the way of strategy, you can suddenly make your body like a rock, and ten thousand things cannot touch you. You will not be moved.



This is the oral tradition. Body like a rock means that as soon as a swordsman reaches the utmost world and is awakened spiritually, he is united with natural law. Like a rock, the law does not refer to neither objects or materials. The meaning of the massive body of rock is, An immovable place, an immovable mind.. A mind which is free from other things, a natural, peaceful, free ranging mind.

This state of mind is similar to spiritual world of Shinran shown in notes from the Tanni-Sho.: Mugi o motte gi to su. (In order to recite the name of Amida, the practitioner must recite it with the other power (referring to the power of a Buddha instead of with the practitioners power). Shinran emphasises the world in which we must surrender human intellect and leave ones judgement to nature.

Thus Miyamoto reached the body of a massive rock and was spiritually awakened. He reached Tsudatsui. What does Tsudatsui mean?
