Long Sword in Chinese / Japanese...

薙刀 is the Japanese word naginata.

A naginata is a special kind of halberd or long sword carried by some Samurai and other warriors. It is still used ceremonially in some schools of martial arts.

Miyamoto Musashi is probably the most famous Samurai in all of Japanese history.

武蔵 is the short title for a man long in legend. While coming from a lower class, his new sword and fighting techniques put him on par with the best that feudal Japan had to offer. His long career started with his first duel at age 13!

He is credited with using two swords at once and never losing a single battle in his career. After becoming a Buddhist, and getting older, like many old warriors, he took up a peaceful and solitary life until his death around 1645 A.D.

Note: Technically, Musashi is his given name, and Miyamoto is his surname. However, it's suggested that he assumed both of these names and had a few other names in childhood, as well as being given a Buddhist name. It's hard to know what to call him, as with most Kanji, there are multiple pronunciations. The characters for Musashi can also be pronounced Takezō. But everyone in modern times seems to know him by the name Musashi.

This text is the ninth chapter of the Daodejing / Tao Te Ching.

The text reads:
持而盈之、不如其已。揣而梲之、不可長保。 金玉滿堂、莫之能守。 富貴而驕、自遺其咎。 功遂身退、天之道。

This classical Chinese passage comes from the Mawangdui (馬王堆帛書) text.
