entrain the brain: "Rhythm, melody and harmony stimulate several areas of the brain, suggesting that music could be used to help repair everything from damaged speech to damaged creations, researchers say. Classical music training may also enlarge parts of the brain, researchers said recently at the Society for Neuroscience annual meeting. Scientists have long wanted to know how the brain responds to sound and rhythm, how musical studies affect brain wiring and how the brains of the musically talented differ from those of the nonmusical. 'Undeniably, there is a biology of music,' said Dr. Mark Jude Tramo, a neurobiologist at Harvard University Medical School...'Some day this research will help us to understand how different types of music can help in different kinds of neurological disorders,'" (Anne) Blood, (a researcher at the Neurological Institute and McGill University in Canada) said."

butterfly:

"Her spirit was really that of a butterfly, so confessed a woman to a monk in a Japanese Noh play...The cycle of seasons rotates from spring, to summer, to autumn; now in winter only the frozen white chrysanthemums remain; but nearby dances the butterfly, like a turning

Little by little, she withdraws from us: 'See her wings wavering with whirling circles of mists;/ See how her figure gradually disappears in the morning haze.'" "The Dance of the Butterfly." S. Lonsdale, Animals and the Origins of Dance. New York, 1982.

“One example I really like is the Bicyclus butterfly. The butterfly actually grows into two different forms depending on what season it's raised in. This butterfly is found in Africa, and in the summer, the rainy season, the butterfly will be green, shiny, and interesting, and in the fall it'll grow into a dull brown. It doesn't do this by looking around at the other butterflies, it just does this on the basis of the temperature. If you take a single butterfly alone, raise it by itself in a lab, and control the temperature, you control which genetic switch gets turned on. So the butterfly will go this way in one environment and another way in another. The genome is giving the butterfly two different choices, two different opportunities. It's not dictating, 'You must take this form'; it's saying, 'If you're in this situation you can take this form, if you're in this other situation you can take this other form.' When you reflect on that, and think about human psychology, that means that our genes aren't dictating that we have to be a particular way. It's specifying different ways in which the environment might interact with us.” G.F. Marcus, The Birth of the Mind. New York, 2004.

a bear:

Polar Bear Dance

This is how the polar bears
Dance the whole night through
But be careful when you stamp the ice
Or you might fall right through!

Clap your hands
Dig the beat
Then turn around and stomp your feet.

there is nothing: R. Caillois, The Writing of Stones. Charlottesville, VA. 1985. Franz Boas expressed the basic spiritual beliefs of the Indian cultures of the Northwest Coast of North America as being: "All nature, the heavenly bodies, rocks and islands, waterfalls, animals, and plants are beings of supernatural power whom man can approach with prayer, whose help he can ask, and to whom he may express his thanks." F. Boas, Kuakiutl Ethnology. Chicago, 1966. p.155.

humming: "It is notoriously difficult to convey the quality of (sasquatch) sounds with written words. 'High-pitched' is a common description, but just how high is not clear. 'prolonged' is also a relative term unless it is actually timed. We also hear about vibratos, rising and falling pitch, multiple tones simultaneously, and a wailing sound (whatever that means). Comparisons with the vocalizations of known animals doesn't help either. They generally do not sound like dogs barking, cats screeching, or elephants trumpeting, but where does that leave us?" G.S. Krantz, Bigfoot Sasquatch Evidence. Blaine, WA., 1999. p.133.
