Actually is an encyclopedia on emptiness. There are all in this book. All about the schools, the different approaches and all you need to know. But most important is the way they are presented in a fantastic writing and an almost poetic language. For absolutely beginners hmm they should had to inform in some way about emptiness, read some articles, watch some teachings. As soon you have done this, this book is the step you need to do. To my poor opinion. A big thank to the Teacher, the Translator and the Editor, wonderful job.
