To slow down, we need to open up to what is right before us.
To speed, we shut all our doors and windows and just zoom.
The zooming can be a defense mechanism, a habit, or a combination of both.
When we are open, we have no choice but to slow ourselves. Speeding in an open state would be dangerous and uncomfortable.
A good place to practice being open is in final relaxation pose, Savasana.
Imagine as you lie on the floor that your body, mind and breath are open like a window, and let the breeze come in and ruffle your curtains.
Remember that you have nowhere to be and nothing to do but to just lay there, open.
