[EX Q]: While this book is very good on providing scripture quotations, the commentary is dated and extremely biased. If this book were to be shared with people of non-Mormon faiths, they would become very defensive and rightly so. The author's invective toward the Catholic faith is appaling. Many Mission Presidents do not recommend this book. It could be dangerous in the hands of the untrained.
[EX A]: Negative

[EX Q]: Naader was my first yoga teacher. When we moved out of state, this video was my link to the best yoga routine I have ever done. I tried other instructors and other videos, but Naader's approach is the best -- a balanced mix of yoga instruction and inspiration. I have shared this tape with many friends (who then bought their own copy!) and they all agree that Naader's instructions are easy to follow and the pace is slow enough that beginners can figure out what is going on before the next pose; but not so slow that experienced students get bored. Furthermore, since he is doing the poses along with the student, he knows just when to offer that extra word of encouragement when you are about to give up! I find something new to ponder each time I listen to this tape. Naader's words are from the heart and they reach out to touch your heart as well as your body. Buy this tape and use it!!
[EX A]: Positive

[EX Q]: For years and years, I always had to watch A Charlie Brown Christmas on broadcast television. I could never miss it! I finally missed it this year, and had to buy the DVD. Now, I will still watch it, even in the dead of summer. Even though there's nothing extra on the DVD, it's still fun to have it around for whenever you feel like watching it! A must have for kids and adults, alike!
