The Inner Caves

Sit comfortably and close your eyes. The body has many small caves, the chest, the belly, the mouth, the ear, even the small space behind each eye. Choose one, the chest is a good place to start. Sense it not as an organ filled with flesh, but as a quiet hollow holding open space. Stay attentive to the openness, not to anything inside it. After some time, move to another cave and do the same. Each one is a small sky in its own right. The body is not as solid as it seems.
