What meditation book/cd/dvd do you recommend for a martial artist?
I'm developing my library and semi-permanent routine right now. One thing I really regret is that even though I've been practicing on and off for nine years (With both traditional arts and combat sports), I never got into meditation, even though I always knew of its benefits. Today I was browsing through amazon and other sites looking for books on functional strength, chi development, yoga, and meditation. I've pretty much made up my mind on the former two, somewhat on the third, but I am really unsure about the last one.
What do you recommend based on your experiences?
