This book is for those who really want to master the core teachings of the Buddha and who are willing to put in the time and effort required. It is also for those who are tired of having to decipher the code of modern and ancient dharma books, as it is designed to be honest, explicit, straightforward and rigorously technical. Like many of the commentaries on the Pali Canon, it is organized along the lines of the three basic trainings that the Buddha taught: morality, concentration and wisdom.
