Understanding the principles underlying a Zen art is not based on cognitive or intellectual understanding. Rather, it is based on an intuitive awareness of the underlying principles of the Universe as they apply to that particular art. It is a form of Zen insight as it applies to that particular activity. For that reason, Leggett describes the Ways as "fractional expressions of Zen in limited fields."5
Because they are formless, the underlying principles of an art cannot be fully described nor directly taught. The philosophy of teaching in the Zen arts is to teach underlying principles through the repetitive practice of techniques. The techniques of the arts represent formalizations of the masters' understandings of the principles. They can be seen as approximations of the underlying principles. Thus, hassetsu is a set of techniques that are at best approximations of the naturally correct way to shoot an arrow. These techniques can only bring the student to a certain point. Each student ultimately must see into those underlying principles by himself. This can only be done by endless repetition of the eight stages of kyudo. This leads to a deeper explanation of the saying "thousands of repetitions and out of one's true self perfection emerges." In kyudo, as in the other Ways, Zen understanding—discovery of one's true self—comes only through disciplined, repetitious practice.

Breathing, Posture, and Concentration
Zen without realization of the body is empty speculation.
Omori Sogen Rotaishi
During my first week at Chozen-Ji, Tanouye Roshi gave a special lecture to the four of us who were live-in students. The topic of the lecture was the principles of zazen. It was then that I first heard the above quote of Omori Sogen Rotaishi. It is a fundamental reality of Zen and a corner stone of the philosophy of training at Chozen-Ji. The statement emphasizes that Zen is not just a philosophy or an intellectual system; Zen realization is physical as well as mental. This is a difficult concept for many Westerners, especially those exposed to Zen by books only. In fact, it is common for books on Zen to begin with caveats about overemphasizing the value of words. Unlike some of the other sects of Buddhism and other religions, Zen does not stress the study of written scriptures. Direct experience and action are the important things to the Zen student. The Zen student is not asked to accept to doctrine on faith. Rather, he is asked to train so that he might have personal experience of the Oneness of the Universe. The key to this experience is the discipline known as zazen. Zen training has no real significance without it.
The process of zazen has been traditionally divided into three aspects: regulation of posture, regulation of breathing, and regulation of mental activity (concentration). Actually this division is only a convenience for the sake of explanation. In practice zazen is the unification of breathing, posture and concentration. Each aspect affects and is affected by the other two. In the Ways, one finds these principles of breathing, posture, and concentration applied to specific activities.
I will now discuss in turn the three component processes of breathing, posture and concentration.
BREATHING
The importance of proper breathing in Zen cannot be overstated, yet the concept that breathing can be a key to spirituality is still a foreign one to most Westerners. While Western people may accept the importance of breathing in athletic endeavors or in relaxation exercises, they do not generally see breath control as a prerequisite for a spiritual experience.
The major differences between breathing in Zen and what most people would consider "normal" breathing is that in Zen it is much slower and is controlled by the muscles of the lower abdomen, not those of the chest. The average person breathes at a rate of approximately 18 respirations per minute. Zen masters have been found to breathe at a rate of 4 respirations per minute or less during zazen.
In order to understand the nature of abdominal breathing in zazen, it would be helpful for me introduce two important Japanese terms that are generally unknown to Westerners. The first is hara. Physically, hara refers to the entire lower abdomen, the part below the navel. The second term is the tanden, which is the point approximately one and one half inches below the naval and is the center of the hara. In the Zen tradition, the tanden is seen to be the center of the person, both physically and psychologically. Physically, it is the person's center of gravity. Psychologically, it is seen as the center of the personality.
To say that breathing in Zen is abdominal is to say that it is controlled by the muscles of the hara. Inhalation is accomplished by relaxing the muscles of the hara. This automatically relaxes the diaphragm and air is effortlessly brought into the lungs, just as relaxing the bulb of a medicine dropper draws water up the pipette. The result is that the lower abdomen protrudes. Once the lungs are full, the person bears down on the muscles of the hara and begins the exhalation. This initial bearing down at the beginning of an exhalation is referred to as "setting" the hara. The exhalation lasts considerably longer than the inhalation. The feeling is that the air is being forced directly downward into the hara. Actually, the
