This does not mean that every student must involve himself in complicated metaphysics but these laws of Material Nature still exist and cannot but become clear during the course of study. Kendo in itself is a vigorous and healthy activity, developing a strong physique and sharp mind. There is no reason why it cannot be practised and enjoyed purely and simply as a sport, or interesting game; even just for exercise. Kendo also has within itself the capacity to include the deepest significance of life and the highest goal of human conception. The student should concentrate firstly on the purely physical aspect of training, since interest in other aspects will occur naturally as they become problems.

The student involved in the sheer physical problems of training will scarcely be aware of his mind, but once the body is reasonably under control it will be seen that the mind is the real bar to progress, for one reason or another. The human being consists of both a spiritual and physical side. Too much concentration on one aspect will lead to an unbalanced life and the student should attempt to develop both parts equally. The student who is too prone to think, should train harder and with greater regularity whilst the student more sluggish of thought should strive to improve his mind and increase his intelligence by thinking things out, and reading.

Once past the first initial stages Kendo is a battle with oneself to catch the mind and force it to obey the will. Over the years the student will pass through periods of elation and depression, keen enthusiasm and lack of interest. The main object is to overcome all difficulties and to press forward with a firm mind and iron will. The student who misses classes because he cannot be bothered to attend, feels tired or thinks that he is getting nowhere has defeated himself from the very beginning. The senior grades and masters are merely those who have had the tenacity of purpose to continue in the face of any difficulty.
