Dr. Masaru Emoto -- whose work is featured in the cult film on the spirituality of quantum physics, "What the Bleep Do We Know?" -- is involved in study positing that water can "carry" our emotion, that our thoughts and feelings affect physical reality.
Emoto (interesting name) developed a technique using a powerful microscope in frigid conditions, along with high-speed photography, to photograph newly formed crystals of frozen water samples. He discovered that crystals formed in frozen water reveal changes when specific, concentrated thoughts are directed toward them.
Water from clear springs and water that has been exposed to loving words shows brilliant, complex, and colorful snowflake patterns. In contrast, polluted water, or water exposed to negative thoughts, forms incomplete, asymmetrical patterns with dull colors.
(The illustration of this post is the crystal, "Love and Gratitude.")
By producing different focused intentions through written and spoken words and music and literally presenting it to the same water samples, the water appears to "change its expression." [edit and addition: It isn't that water has emotion. It is that its physicality -- its molecular definition -- can be influenced by human emotion. The theory is that the electrochemistry of our thought processes can influence water's molecular footprint.]
If you haven't seen "What The ..." I hope you will. These thoughts are dealt with in a fascinating manner. Humans and the earth are mostly comprised of water. If you accept that thought can shape crystals made of water -- as you are mostly made of water -- imagine.
