I have followed Dr. Masaru Emoto's studies on changing the molecular structure of water by intention or thought. He has found that the molecular structure of water can be changed by an energetic condition. (I.E. thought, intention, prayer-- it has energy.) And his findings are really interesting. Dr. Emoto says:

"In late in July 1999, we had a ceremony offering prayer to the biggest lake in Japan called Lake Biwa. Because Lake Biwa is in the shape of a female uterus, it has traditionally been called the “Mother Lake.” Unfortunately, Lake Biwa was extremely polluted and every year it would give off a foul smell. I thought this was an unacceptable situation because Lake Biwa is a symbol of the female body, and I thought we had to do something about that. So 350 people got together around the lake, and we offered a great invocation. About a month later there was a fascinating article in the newspaper.

Paper stated, “Only this year, a foreign species of alga that had been
notorious for many years for growing unusually in a large
quantity and making a foul odor did not show up, and the city
office, that had gotten so many calls of complaint from the local
residents for many years, did not receive any call this year.”

Every year after that date, the city office received more than 300 calls about the smell, but only that year, they did not receive any calls. Since then, a group of people have been getting together to offer a prayer to Lake Biwa, and I understand that the lake is getting cleaner every year.”

He also says, “I started taking pictures of water crystals and that was the same time I started to discover the power of prayer. It doesn’t matter if we show written words to water or if we say some beautiful words to water such as “love” and “respect.” The water responds beautifully.”

Very cool stuff! I have pictures posted in my photos, of the lake water's molecular structure before and after the prayer conducted by Dr. Emoto and the group. His book, "Love Thyself" has this and several other experiments, with really lovely pictures.
