I used to be able to lie down on the grass and relax into the very center of my solar plexus and feel the earth spin. Really. My whole body would tune to the thrumming velocity of the earth twirling on its axis very fast, gravity pressing my body into the ground. Then one day I couldn't do it any more. Now, I'll lie down like I did today after a run, and for a brief moment I'll feel myself almost slip to that place, but then I'll snap back into myself, like snapping back from almost falling asleep. Has this ever happened to you?
