The Sky in the Heart

Sit with eyes softly closed. Bring your attention to the centre of the chest, the heart-space. Imagine that inside this space there is no organ, no flesh, only a wide open sky stretching in every direction. Let that inner sky have no edges. Whatever thought or feeling passes through is just a cloud crossing it. The sky does not move when clouds cross. Neither do you. Rest as the sky, not as the clouds.
