“If I don't wield the sword,
I can't protect you.

If I keep wielding the sword,
I can't embrace you.
-Ichigo Kurosaki”

Go Rin No Sho (1645), The Water Book
Context: Knowing the Way of the long sword means we can wield with two fingers the sword that we usually carry. If we know the path of the sword well, we can wield it easily.
If you try to wield the long sword quickly you will mistake the Way. To wield the long sword well you must wield it calmly. If you try to wield it quickly, like a folding fan or a short sword, you will err by using "short sword chopping". You cannot cut a man with a long sword using this method.

Variant: He who does not fear the sword he holds is not worthy of holding a sword.
-Hisagi Shuuhei

Go Rin No Sho (1645), The Ground Book
Context: There is no fast way of wielding the long sword. The long sword should be wielded broadly, and the companion sword closely. This is the first thing to realise.
According to this Ichi school, you can win with a long weapon, and yet you can also win with a short weapon. In short, the Way of the Ichi school is the spirit of winning, whatever the weapon and whatever its size.
