This video is very good, straightforward Dharma — from John Daido Loori, Roshi, and abbott of the Zen Mountain Monastery in upstate New York. The beginning intro is super cheesy, but don’t be dissuaded by that. As soon as the roshi starts to speak, I think you’ll see that this is good stuff (introductory Zen; “eight gates”).

This comes via Dharma TV, and as you might guess, you’ll find other teaching videos there as well. (I know I found a link to this on another Buddhist blog, but I forget which one. If it was yours, let me know, and I’ll add a link here.)
