Time was when traditions were quite separate. There was little cross-pollenation. The American way of 'using what works' has changed all that. The traditions of yoga and meditation inform each other in powerful ways. I meet many people who say, "I love yoga, but hate meditation," and vice versa. I'm excited to see how movement and stillness practices influence each other and open up new worlds.
The Kripalu Center training we just completed honors how important it is to find balance between energy and awareness (sanskrit words, 'prana' and 'chitta.') Sometimes we need to move energy. Sometimes the most balancing thing is to focus and calm the mind, gathering your attention in one place.
