Learn to sit comfortably on your haunches, palms together, elbows driving the knees apart. Feel the mingmen push back and the lordosis disappear. The upper part of the spine above the mingmen extends up over the head and down into the heart and the lower part of the spine below the mingmen extends down under the body and up into the dantien. Heart and dantien move towards each other. The mind naturally quietens being this close to the ground, and you feel settled and contained as though someone has thrown a sheet over you. There is a sense that this is home, even more than sitting on your cushion.
