The second series of Ashtanga Vinyasa Yoga, with traditional vinyasa, sanskrit counting and options for the more difficult postures. Also known as Nadi Shodana, or nervous system purification, the Intermediate Series progresses with more back bends, leg-behind the head postures and a number of head-balances to finish. This sequence has a direct effect on the nervous system which can further aid the development of self awareness - from the physical practice to the energetic practice.
