Yoga Beauty Body is my favorite, I bought it, did it one night, and immediately ordered 3 more of their dvds, now I have almost the whole collection. I guess I wouldn't say Yoga Beauty Body is focused on relaxation, but it's an extremely good introduction to the whole kundalini concept, there are a good set of basic ky exercises, good meditation, and it really gives you the flavor of what the RaviAna workouts are like. I think you would experience relaxation after the dvd is over, as a sort of side effect, along with a calm energy, deeper sleep, glowing skin, etc. I LOVE RaviAna, I've been doing ky for 6 months and always feel I learn something new no matter how many times I've done a particular workout
Whatever you decide, enjoy!
