I often have my students work in this way, drawing the tailbone into the center of the room, groins toward the wall, and hands moving down to the shoulder blades.
This made me realize that I am often very focused on alignment - to the point of perfection - trying to get my hands as close to the floor as possible, tailbone so very forward, groins back, tops of the shoulders, etc.
Tomorrow, I plan on attacking the pose in a softer way- without attacking. Keeping it soft and without judgement. Relaxed. Lets see how it goes.
