Breathe as if it were the most interesting, luxurious thing that could happen to you. Because it is.
Before you get out of bed and again after you get back in for the night, put one hand over the place where your ribs come together and the other over your soft low belly.
The first few breaths will have lots of effort and striving. You'll be trying to breathe, so you'll breathe deeply or shallowly. That's okay. Go with it. When you have a breath that comes like a visitor, just enjoy it and then watch it go. Linger in the spaces. Enjoy the not trying of it. Enjoy the motion without effort, the wildness of it and the rhythm. Enjoy paying attention to your constant but neglected companion and watching it come to exuberant life under your caring gaze.
And promise to visit again.
