Peter Carlson writes: Wisdom Wide and Deep by Shaila Catherine follows an earlier book by this author, Focused and Fearless, which described the training in jhana practice under the tutelage of the Pa Auk Sayadaw. The current book, published in 2011, combines descriptions of Buddhist salvational psychology, the Abhidhamma, with practice tips on how to combine tranquility (shamatha) meditation with insight (vipassana) meditation. This is a very comprehensive approach to the subjects, and will likely be a standard practice manual for many serious meditation students.
