Urdhva Dhanurasana

Yoga Chikitsa (योग चिकित्सा, Yoga Cikitsā) is the Sanksrit (संक्सृत्, Saṁksr̥t) name for the primary series and it can be translated as Yoga Therapy. Therefore this series purifies and heals the body.
The first or primary series forms the basis for all subsequent series. Superficially seen it may seem the easiest of all six Ashtanga Vinyasa Yoga series. It is however the most difficult one; it is the series first learned by every Ashtanga-Yogi; this is where one becomes familiar with the Vinyasa System and gets used to everyday Yoga practice. The following series do not bring anything that is relatively new. Only a couple of new postures integrate into the system one is already familiar with.
