Due to the diversity in Buddhism, its essence remains a puzzle. This book investigates the Buddhist path to liberation from a practical and critical perspective by searching for patterns found in the Pāli Nikāyas and the Chinese Āgamas. The early discourses depict the Buddhist path as a network of routes leading to the same goal: liberation from suffering. This book summarizes various teachings in three aspects, provides a template theory for systematically presenting the formulas of the sequential training of the path, and analyses the differences and similarities among diverse descriptions of the path in the early Buddhist texts. By offering a comprehensive map of the Buddhist path, this book will appeal to scholars and students of Buddhist studies as well as those practitioners with a serious interest in the Buddhist path.
