Form Is Necessary. Attachment to Form Is Not.

Here we encounter an important distinction between form and attachment to form.

Form is necessary for training. Attachment to form becomes an obstacle when form must be used in reality.

A swordsman therefore learns a stance in precise detail, but must train deeply enough that the stance no longer needs to occupy conscious thought at every instant. In the language of learning:

「有構無構のおしへの事」

This becomes even clearer in one of the most important teachings in 五輪書: Ukō-Mukō no Oshie no Koto, The Teaching of Having Stance and Having No Stance. moromoro writes:

Although the sword may appear in one of the five directions, its placement must respond to:

• 敵の縁: the relationship with the opponent
• 所: the place or spatial condition
• けいき: the condition, atmosphere, or timing of the situation

The sword is positioned according to reality, not according to a rigid diagram.

This is where 有構無構 becomes a philosophy rather than merely a technique of sword positioning. moromoro explains that:

• 上段 may descend into 中段.
• 中段 may rise into 上段.
• 下段 may rise into 中段.
• A side position may transform into 中段 or 下段.

The five stances are therefore not five isolated boxes. They are points along a continuous field of movement.

There is stance, yet there is no stance

And so we arrive at the famous principle:

This is not an irrational contradiction. It distinguishes between the stance that appears physically and the stance that the mind clings to conceptually.

In simpler terms: 構 (kamae) remains. But 構えようとする心, the mind that tries to “maintain a stance,” must disappear.
