Thunderbolt (Vajrasana)

Begin on hands and knees. Bring the ankles and knees together, and gently move the hips back to rest on your heels. If this is uncomfortable for your knees, place a block between the feet to sit on.

Vata Focus:

With a gentle focus, release the pelvis and settle into the breath. 

Benefits:

Good for the knees, digestion, and moving energy down (apana vayu).
