As well as increasing strength in the legs, parivrtta baddha parsvakonasana stimulates the abdomen and stretches the muscles of the upper and lower body. It can also help to increase whole body balance, rooting and grounding. It is a challenging posture which may take time and patience to master. This can help to teach the yogi the importance of balancing effort with surrender.
Traditionally, parivrtta baddha parsvakonasana, like all twisting postures, is associated with the manipura chakra. Working with this chakra is said to help increase feelings of self-confidence and worthiness. It can help the yogi to feel less fearful and negative. Twists are also associated with building inner fire and personal power.
