Via my recent adventure with the terrier, I've been reading and very much enjoying David Loy's Nonduality: A Study In Comparative Philosophy. There's much that I've appreciated about this book, which was originally published in 1988 by Yale University Press, and which draws forth the thread of commonality between three spiritual paths: Taoism, Buddhism and Vedanta.
Perhaps most significant for me personally was that it helped me to resolve -- at least partially -- a kind of cognitive dissonance I've been experiencing, in relation to Mahayana Buddhism and Advaita Vedanta: how these two traditions on the face of it seem in so many ways diametrically opposed, yet have such a similar feel to them. And, since I love noticing what the various nondual traditions have in common, I was quite receptive to Mr. Loy's project.
I've written a review, which ended up quite a bit longer than I had anticipated, so I've divided it into three parts:
Part One: Five Flavors Of Nonduality
Part Two: Nondual Action & Nondual Thinking
Part Three: Philosophical Difference, Identical Nondual Experience
Enjoy!
