Starting with the "Art of happiness" of His Holiness the Dalai Lama I became very interested in the buddhist view to the world. Not speaking of it as a religion, but a psychology.
Getting a little deeper into that field, there's nearly no way to get around Alan Watts, Ajahn Brahm, Gil Fronsdal and of course Jack Kornfield. Like very little westerners he can produce the wisdom of the great asian monks to our western world, perfectly translating the sense.
All areas that are basically of interest and needed for a complete understanding are covered in that book and at least described in a way so that you have a solid rock to stand on. Jack Kornfield has a very interesting way of speaking and doesn't miss the points to place a funny comment to break up with getting too serious.
After I listened to that book I felt well prepared for keeping up "studying" buddhist psychology and I would say, that it has been very much easier to move on that if I hadn't listened to it.
Moreover it is so full of interesting facts, that I consider it a book to listen over again.
To german listeners: I recommend to hear that book in this original tongue if possible. The translation to german is good, but doesn't catch up to the original in my opinion.
