Aligns and releases the spine
Take a six foot long piece of fabric about 1″ wide and insert through a hole at the top of your head. With your right hand feed the cloth all the way down through the center of your spine and out your Coccyx. Grab the end with your left hand and gently pull back and forth, cleaning out your spine.
This is a difficult visualization but give it a try. It is an awesome sensation and really does clean things up. Aligns and releases the spine.
