When I was in college at the University of Pittsburgh, I took a fascinating class called "Mysticism: East and East" that compared the contemplative traditions of Yoga and Orthodox Christian hesychast prayer. As a practicing Buddhist at the time, it was an eye-opening class.

I don't really know how to present a concise summary of the class, but I did find this paper by my teacher which sets forth an overview: http://www.doiserbia.nb.rs/ft.aspx?id=0350-08610802171B

Now of course Orthodox hesychasm is about communion with a person, whereas eastern meditation is typically not (Pure Land schools of Buddhism are more in line with Judeo-Christian concepts of prayer, though). But I think that there is some common ground for dialogue, and perhaps this paper may be of interest to you or others who enjoyed the original article and are interested in other practices.
