My teacher, Mary Dunn, often used food analogies to describe actions in the asanas. For seated twists she would say “do them as you would stir soup-from the middle of the pot not from the outer periphery. “
“B.K.S. Iyengar describes twists as a “squeeze-and-soak” action: The organs are compressed during a twist, pushing out blood filled with metabolic by-products and toxins. When we release the twist, fresh blood flows in, carrying oxygen and the building blocks for tissue healing.
As you perform twists, your attention is drawn into the stable, unmoving center of the pose. This can give you the ability to stay centered as the hubbub of the world swirls around you.” …..
