Advanced Xingyi Energetics openly and directly teaches the specific practices and "enablers" for maximal internal energy generation based on the Xingyi mechanics. There are thousands of books, videos, web and zoom trainings, and real-life classes that can instruct you on the physical mechanics of Xingyi. They will also mention some of its philosophical theories, and may throw in one of the many definitions of "qi" as internal power. But none of them will instruct you on the precise, yet simple and straight-forward, best practices for tuning your mechanics to maximum sensitivity and absorption of the incredible internal energies which the simple-appearing techniques of Xingyi can ignite, once they are understood fully. The author owns perhaps the most extensive collection of publications on Xingi, in multiple languages, in the world. In not one of those books, nor in the great classical writings of the 19th century Xingyi masters and their prominent students, are these specific training accelerants revealed. These practice methods were personally taught to the author by an obscure but extremely powerful combative master almost 50 years ago, and recorded in a hand-written transmission document. AXE is a massively enhanced, far deeper, nearly total re-write of my earlier elementary treatment of Xingyi basics as an energy art ('Radical Xingyi Energetics', 2014). This book does NOT teach the mechanics and physical dynamics of the Xingyi techniques in detail. For that you will need to work with a qualified teacher "in real life". However, this book is absolutely essential for anyone who has an established Xingyi practice routine. It is also an invaluable source of inspiration for beginners or Xingyi-curious people to see what all the fuss is about. It's a uniquely practical and enlightening open view of what's under the hood and why the mechanics of Xingyi alone are not at all what makes this discipline the standout, premier art, the GOAT (Greatest Of All Time) when it comes to internal energy cultivation, deployment and the plain fun of infusing yourself with the unimaginable power experiences that Xingyi triggers inside you.
