Though the abhidharma is recognised as one of the major topics of the Buddhist teachings, up until now there have been few translations of any of the great texts on it available in a Western language. This book gives thorough explanations of all the fundamental concepts and terms found in the Buddhist teachings. It presents the nature of the phenomena we experience, describes the karma and afflictions that create suffering, and shows the factors of the path that lead to liberation. It is like an encyclopaedia of Buddhism that thoroughly explains the meaning of the many different technical terms found in the sutras, vinaya, and other Buddhist teachings -- if you are wondering what something you have read in a Buddhist text really means, there is a good chance it is explained in this book. It thus provides an invaluable aid to students who want to deepen their understanding not only of the abhidharma, but of all the Buddhist teachings.
