Purna Vajra Asana (Completed Thunderbolt Posture) is performed by opening the feet apart and sitting between the heels on the floor.
- The feet are next to each other on the same buttock.
- This position stretches the lengthy sinews of the legs and massages the thighs and calves deeply.
- It's ideal for someone who spends a lot of time walking, riding, or driving.
- If sitting in Purna Vajra Asana is challenging or unpleasant, return to Vajra Asana after a few seconds and alternate the postures as needed until sitting is pain-free.
All of the foot postures are ideal for deep breathing, especially Adham Pranayama, or low breathing, which is linked to improved circulation in the pelvis and legs.
