I’ll have to look up his book, “Living Buddha, Living Christ.” I’ve seen it for sale but I dismissed at as probably a New Agey type book. On second thought, I assume because of the author that the book has depth to it and maybe it can help an outsider understand Buddhism and help one understand how Buddhists see Christ. I do think that Buddhism and Christianity are incompatible but it is good to understand how others see things, whether we agree with it or find it mistaken. We often live in a bubble and assume we know how others think.
