Be well warned ; this little book is , @ times , very hard going ( progressivly with each chapter ). However , there is a very good reason for this : the teachings a given very succinctly and they are/appear to be rather profound explainations of extremly important buddhist concepts .
That said , this book has proven to be of great help to my understanding of impermanence and the role thought plays in our view of reality . After reading this book i feel i understand a few others much better ; i now "know" one meaning of what , previously , opaque comments were intended to convey .
Highly recomended .
