I actually did not like the Wai Lana relaxation video at all. It was a lot of slow leg lifts and she changed outfits between every posture and they were really weird. And I couldn't understand what she was saying and she sang a song in the end. I just thought it was kind of cheesy.
I do love Eoin's Pure and Simple, and he isn't very spiritual, he has a really nice voice though which is nice to relax too. It isn't too hard because you can watch the beginner track and it has this great feature where you can turn on a breath track, that way you can make sure through the whole thing that your breath stay in tune with what your body is doing. I LOVE LOVE it. Whenever I finish I have that "yoga high"!
Ali MacGraw - Yoga Mind & Body is a classic, yoga guru Erich Shiffman helped design it and it is popular among most people and you can find it in a lot of places.
Yoga Zone Stress Relief- All the yoga zones are popular because they are really good, they have a lot of instruction. The best part is if you have a Ross store you can usually find them for around 4 dollars.
Altar of the Heart- is maybe my favorite yoga video, but it is pretty long and you can only buy it from Tilak Pyle's website. It is really beautiful and really relaxing.
Good Luck and let us know what you end up with and if you like it
