"Water of earth [liquid] is compressed into small volume while water of the heavens [etheric vapor] is expanded thousands of time in volume. Each condition is the opposite half of the cycle of water.
Water [etheric vapor] vapor is water turned inside-out. It again becomes [liquid] water by turning outside-in. Expansion-contraction sequences result from this process." [Walter Russell, The Secret of Light, pages 162-163]
