The Secret Life of Water, by Masaru Emoto. In The Hidden Messages in Water, Masaru Emoto described how water can absorb, hold, and even retransmit human emotions, and underlined his theory using high-speed photos of frozen water crystals that showed changes when specific, concentrated thoughts were directed toward the water. Extending this idea, The Secret Life of Water focuses on how prayer can affect water — and more — in a curative way. The book's central goal is to promote peace within the reader and around the world through the use of prayer. Covering the various aspects of hado, or life energy, it focuses in-depth on hado's "flow" aspect, and on the consequences when human desire, pride, and ideology interfere with "flow." According to the author, water can act as a mirror reflecting the human heart — and the current water situation is serious. He argues that prayer is the first step toward healing, and documents the power of prayer when people gather together, outlining several experiments in which water has revealed visually how prayer can change the world.
