Read this book aloud to my partner in the morning before meditation, the second time I read it. It's amazing on many many levels. It anticipates Ratnaguna's book on reflection. It lays out his essential teachings in so many ways. Sangharakshita is a genius. He wrote the survey in 1947, and he's still cranking them out. Of course this book was based on his seminars on the Satipatthana Sutta, so they're really edited, and then he approved of them, so maybe he added in more and whatnot. Quite amazing book. I'll put that up there with my 5 favorite Sangharakshita: A Survey of Buddhism, Know Your Mind, The Yogi's Joy and Three Jewels. Of course if you're new to him, I'd read The Essential Sangharakshita, then branch out there, but follow your interests as always.
