I found this (Arahattamagga Arahattaphala - The Path to Arahantship) during a short retreat recently at MBMC, and some parts of it really hit home, in ways other books and teachers haven't. For me some essential aspects are much more clear now, particularly regarding the knowing nature of the mind and it's role in both the development of samadhi and insight. He also emphasizes the importance of trusting one's own process which I like. Some parts of this book really rock.

Interesting that he recently died. I'm in Thailand currently, and there's a network television station that's been devoted to him for at least a few years now, mostly his dhamma talks and meditation instruction. He's also been involved in helping the government and
people on a national level.
