Translated versions are not easy to obtain.
some you will find in translated and reinterpreted versions.
But like most old books, they are not updated, translated etc.
To that end, people out there that actually do research are helpful. Yang Jwing Ming as translated many old manuals and modernized the presentation of the material. Dr.Meir Shahar has recently released a really great resource on Shaolin that indicates much about the manuals etc, who wrote them and there is a large list of citations in this book as well. Worth investigating.
It takes real effort to dive into this stuff. But it's not that it isn't there to dive into. But do you have a few years?(decades) lol
You could train to fight, meditate, spar etc and do it well without even knowing about any of it. We are all human and though some of us work hard to do special things, no one has anything particularly magic to offer.
To be sure and this has been indicated several times now, the Ancient Shaolin were most well versed in work with the staff. Little is available on pugilism, but there is some. Anyway, I would recommend reading Shahar's book an take it from there. The citations are many. Those will keep you busy for a long time.
