At different times in 27 years of practice, I've had affinities for different poses or types of poses. Early on, backbends were my passion. I still love them, but since then I've delved into standing poses (originally NOT my favorite poses), spinal rotations, and long inversions, among others. One pose has been a constant favorite for me from the beginning: Sarvangasana (Shoulderstand). When I roll up into Shoulderstand, my body immediately says, "Ahhhh." I love the feeling of weightlessness, and I think that going upside down changes my perceptions, not just in the moment, but throughout the day.
What are your favorite poses? What is it about them that you enjoy? What have you learned from them?
