Suzuki basically has written this book, which primarily about Buddhism rather than Christianity, as a way of drawing connections between the different mysticisms present in Christian tradition and how some of these mysticisms share common traits and insights with Buddhism. Not surprisingly, the mystic whom he chooses to do this with is almost exclusively Meister Eckhart. This is, thus, no comparative history but a Buddhist slant on Eckchart's thought and spirituality. It is a slant that might make some Christians uncomfortable but it is interesting nonetheless. This serves a window through which he continues to discussion Buddhist mysticism at large in the rest of the book.
