In Ashtanga Yoga we can practice three series: the first Yoga Chikitsa detoxifies and aligns the body, the second or intermediate series Nadi Shodana purifies the nervous system through the opening and cleaning the energy channels (nadis) and the third Sthira Bhaga integrates strength and grace into the practice, gaining a high degree of flexibility and humility.
Each series must be fully developed and known before proceeding to the next, and the sequential order of asanas should be followed meticulously. Each posture is a preparation for the next, developing strength and balance to advance. When we practice the series of Ashtanga Yoga, which increase the inner fire through the movement, the sequences of postures generate heat and this, in turn, produces sweat. Sweat helps to purify and cleanse the body by releasing toxins retained within the body.
The specific combination of the poses in the Intermediate Series works strongly on the nervous system, so it can have a very different effect on the body than the Primary series or other dynamic yoga classes.
I edited a practice sheet according to the teaching of David Swenson, in the hope it helps practitioners to learn the sequence correctly and in detail. Remember to practice Sun Salutation A+B, the Standing Sequence and the Finishing Sequence for the second one too.
On my website you also find detailed practice sheets for the First Series Yoga Chikitsa.
