I commented earlier that my use of Gorin No Sho is as more of a technical manual for combat than as a guide for training in a formal ryu. So, of course, I have a different perspective of understanding and using Gorin No Sho. What Chris and Mark have said is true in respects to how many times you may have to read it before you begin to understand the lessons Musashi is trying to impart on strategy and other practical fighting aspects within his tome. Constant practice and study is the key. It took me many years to figure out what some of it meant. Other parts came quicker. Then I had, what could be described as, an epiphany moment and I was able figure out most of the passages that had eluded me. As to the influence Buddhism had on Musashi and his authoring of Gorin No Sho, there is no doubt of that. In regards to the necessity of having knowledge from the Buddhist Sutras to understand the book, I will have to more research and read them before I can comment intelligently. Before going to the HNIR website I had never been exposed to the idea that in order to understand Gorin No Sho one must first have an understanding of the Buddhist Sutras. For the purposes of using Gorin No Sho within HNIR it may be an absolute necessity. After reading the Buddhist Sutras, I may have a better understanding of Gorin No Sho than I currently have, but as of this writing, I believe I have, at least a functional understanding of most of the lessons Musashi wished to impart. There are parts that still elude me, and maybe the sutras will help me with those.
