This following article was taking from the Bubishi; an ancient Military Tactical Manual of Chinese origins. It is to be read from up to down, right to left. All eight precepts of this poem relates to how you train in Meibukan Goju-ryu. How do they relate? It is up to you through constant training to figure that out. Some precepts are easier to figure out then others. The third precept is where Chojun Miyagi Sensei came up with the name Gojyu-ryu.
More on the Bubishi
Bubishi (武備志) is the Japanese pronunciation of the Chinese Wubei Zhi, "Account of Military Arts and Science". This is the title of two different Chinese documents.
The first Wubei Zhi was a book produced in 1621 by Mao Yuanyi: a massive compilation consisting of 240 chapters in five parts and 91 volumes, treating all aspects of the art of war.
The second Wubei Zhi or Bubushi was a compendium of topics loosely related to the Fujian-based quanta traditions of Yongchun White Crane and Monk Fist boxing, probably dating from the mid-to-late Qing dynasty (1644-1911.) It contains anatomical diagrams, philosophical essays, defensive tactical strategies, and poetry. No author is known; the book is most likely a collection of pieces from various sources put together by an anonymous editor. It was popular in Okinawa among Okinawan-based quanfa practitioners during the 19th and early 20th centuries.
