This is the definitive watershed work that brought Buddhism to the West and explains it in a manner that's very easy for Westerners to understand. It is a wonderful book that uses a question and answer structure like the Catholic Catechism to enlighten the reader on the Buddhist faith. It covers every aspect of Buddhism and there's much to learn from it whether you are a beginner or a master or from the East or the West. I strongly recommend this book. I got so much out of it. This book answers a lot of very important questions, including ones that I have had for some time. It's been a real blessing to me.

I used this for taping while we were opening gifts for christmas. The remote features are great. This product makes video recording easy and fun.

I love the features and optics of this camera. I love everything about it, except that it really doesn't work and their service is terrible. Many people posted about the humming sound -- I didn't have that problem. But the electrical system was intermittent from the time I got the camera. I've sent it to them three times, and each time they repair it, or claim to. Now it is out of warranty and the battery still doesn't work. So I'll have to buy a new camera and hope that you don't make the same mistake I did -- go with a different camera.
