What do modern disciplines like biology, psychology, and the study of culture contribute to the understanding and practice of a classical meditation like Vipassana? Following the encouragement given to him by the Vipassana teacher, S.N. Goenka, to explain this ancient tradition to contemporary audiences, Dr. Paul R. Fleischman unites science and spirituality, technical language and poetry, logic and intuition in a manner that is as virtuosic as it is understandable. The Power of Small Changes is a collection of decades of public talks and university lectures that speak to readers who have no previous knowledge of Vipassana, as well as to experienced practitioners, using down to earth explanations reinforced by academic knowledge and rigor. While many of the chapters in this book have previously been shared online in various formats, the present collection features newly revised and expanded content, focusing on practical issues like how to maintain daily meditation practice, coming to grips with the monkey mind, understanding the evolutionary biology that meditation utilizes, appreciating the role of teachers, community, and tradition; and preserving its nonsectarianism. The importance of a spiritual, rather than a financial basis for Vipassana, as well as the historical role of the Buddha are also clarified. A uniquely valuable chapter discusses the safety of Vipassana, explaining its contributions and limitations.
