Masaru Emoto (江本 勝 Emoto Masaru?, born July 22, 1943) is a Japanese author and entrepreneur known for his claims that human consciousness has an effect on the molecular structure of water. Emoto’s hypothesis has evolved over the years of his research. Initially Dr. Emoto claimed that high-quality water forms beautiful and intricate crystals, while low-quality water has difficulty forming crystals. According to Dr. Emoto, an ice crystal of distilled water exhibits a basic hexagonal structure with no intricate branching. Emoto claims that positive changes to water crystals can be achieved through prayer, music or by attaching written words to a container of water.
