This is the thesis of H. H. The Dalai Lama. Giving a strong foundation in the basic principles of Buddhism, this book builds to explain in detail the various states of meditation and connects each point to the other for a grand and wonderful whole picture.
This powerful book is short enough to be read in one day, but profound enough to be studied for years. And as always it retains the warm and straight foreward manner in which this wonderful author is known for teaching. Also for those unfamiliar with the Dalai Lama's other books, most of them are compilations from lectures, etc. This book was actually written by him.
Blessings and peace to all beings!
