Query: Excellent stress relief

I have a number of yoga DVDs and also attend a yoga class; however, I find I keep going back to this DVD over and over again. I like the variety of routines to choose from and the instructions/explanations are excellent. She also has a soothing voice, which adds to overall relaxation. I've been battling stress and anxiety for a few months now and have found this DVD to be exceptionally helpful in "letting go" of daily stress and calming my thoughts. Highly recommended!
