Satipatthana: The Direct Path to Realization, by Analayo, is becoming admired as an excellent addition to the already existing commentaries on a fundamental discourse of the Buddha, the Four Foundations of Mindfulness.
Analayo was born in Germany and has been a monk in Southeast Asia for many years. This book combines the scholastic manifestation of his PhD. Studies, combined with his ongoing meditation practice on retreats. It isn’t an introductory book, and has quite a few footnotes, but I think it is quite useful for anyone who wants to really understand this profound teaching as one’s practice of mindfulness deepens.
He just published a companion book, Perspectives On Satipatthana, which expands the depth of personal and scholastic research in particular topics that couldn’t be explored in the context of the earlier book. I’m currently reading the second book, and highly recommend the first book.
