I am interested in the Zdorovye Health System. I see the first series of tapes are available for purchase (BASIC LEVEL of Zdorovye™ 1st Trinity: Movement Exercise: Dvizheniye™ Natural Grace, Postural Exercise: Polozheniye™ Natural Poise, Breathing Exercise: Dykhaniye™ Natural Energy). I put them on my Christmas wish list along with the Effortless Running called Slavyanskiy Byeg™ Natural Carriage tape, so hopefully Santa thinks I have been good this year. However, I do not see the INTERMEDIATE LEVEL of Zdorovye™ 2nd Trinity: Plastichnost™ Natural Suppleness, Raslableniye™ Natural Relaxation, Vibratsiya™ Natural Vibrancy availbale for purchase. My questions are, can I purchase them? If so, how and how much?
