Re: Anyone have good book suggestions on
Two others worth considering:
"On Mastering Aikido", Daniel Linden, Linden Tree Press, Orlando, 2004 (ISBN 0-9746459-0-7) and "Aikido Basics", Phong Thong Dang and Lynn Seiser, Tuttle Publishing, Boston, 2003 (ISBN 0-8048-3490-3). I had to order the Linden book from the publisher, but found the Dang/Seiser book at a local Barnes and Noble.
Both offer pretty good discussions on ki with a bent to explain in western terms. Lynn Seiser contributes here frequently too. Narrowing the paper is an excellent idea as well. Good luck with the paper.
