Exactly. Doing hatha yoga exercises will not turn someone into a Hindu (not that that is a bad thing).
I avoid most all yoga videos/books because I loathe any New Agey stuff mixed in, which most all have, or a lot. I stick with the real classical kind. Most yoga I learned from the great Iyengar book, Light On Yoga. Actually I first did Hittelman’s, then found the Iyengar book. Many people can not learn directly from a book without a human teacher, but if you’re sensitive and pay attention to what your body is doing, it can be done. Aptitude helps.
I started practicing hatha yoga seriously when I was around 26 and did it until RA hit me when I was around 50. I am now well enough from diet and herbs to start it up again.

They are pretty good. Look at Ravi Singhs (sorry if spelling is off a little) book on kundalini yoga. Best presentation of spinal flex postures I have seen anywhere.
I was about 37 then and an out of work construction guy so using a book at home was more appealing to me than taking a class with a bunch of women in it. (Boy was I dumb!) I really felt so bad about being out of work and in constant pain then that I didn't feel like meeting anyone new.
RA is a tough row to hoe. I wish you all the best in dealing with it.
