"Imperturbability results from a balance in the consciousness, and when the desire for all things that we see or have heard of is extinguished." - Patanjali’s Yoga Sutra, 1:15
Saithalyasana is a seated, relaxing pose that is usually done while preparing for other seated asanas like bhujangasana and dhanurasana. This asana stretches the neck and the hips in opposite directions, and also opens up the hip joints. Saithalyasana is a very calming pose that improves circulation and makes the body flexible.
