The Abhidharma, one of the three major text collections of the original Buddhist canon, frames the psychological system of Buddhism, explaining the workings of reality and the nature of the human mind. It is composed of detailed matrixes and lists that outline the interaction of consciousness and reality, the essence of perception and experience, and the reasons and methods behind mindfulness and meditation. Because of its complexity, the Abhidharma has traditionally been reserved only for academic or monastic study; now, for the first time, clinical psychologist Beth Jacobs brings this dynamic body of work to general readers, using practical explanation, personal stories, and vivid examples to gently untangle the technical aspects of the Abhidharma. Drawing on decades of experience as both a therapist and a Buddhist, Jacobs illuminates this classic area of Buddhist thought, highlighting the ways it can broaden and deepen our experience of the human psyche and offering profound insights into spiritual practice.
