[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]: I have not read any of Charlie Smith's other work, so I can't compare this to previous efforts. His writing is poetic, and truly impressive in short bursts. But over the long haul, the poetry interferes with the prose. Words and phrases seem to be chosen more for their sounds and rhythms than for their contributions to plot, and dialogue can be stilted. Imagery is vivid but occasionally self-indulgent. The storyline is interesting at first but eventually grows gaudy and distasteful. The power of Smith's language is his greatest strength, but it is a strength better suited to poetry than novels.
[EX A]: Negative

[EX Q]: I'm a white female who is married to a black man. I'm outraged that she does not agree with interracial marriages. She talks about living in AmeriKKA, but it is her as well who promotes racist views. How are we to live as a nation if people can't be friends/lovers just because of their colour. Obviously we haven't progressed as a nation if we can't accomplish that.
