Dwi Pada Sirsasana (Both Feet Behind the Head Pose) registers as 24* on BKS Iyengar’s 60* scale of difficulty in Light on Yoga. Yep, only 24 stars.
Dwi Pada Sirsasana takes Eka Pada Sirsasana to the next level. In Eka Pada Sirsasana, one foot rests behind your head; in Dwi Pada Sirsasana, both feet rest behind your head. In the full pose, your hands rest together at your heart and you balance on a very small area near your tailbone. As Iyengar explains, “This is difficult and one is apt to fall backwards.”
If Yoganidrasana is in your practice, start exploring Dwi Pada Sirsasana. Start by taking Eka Pada Sirsasana, then start moving the other leg behind your head and placing your hands on the ground. Like me, perhaps your feet won’t get entirely behind your head. Be patient with yourself! Iyengar mentions that, once you get your legs behind your head, you may only be able to balance with your hands off the ground for a few seconds. Work with where you are and, most importantly, laugh when you topple over.
