"There is no way in which to understand the world without first detecting it through the radar-net of our senses . . . Our senses define the edge of consciousness, and because we are born explorers and questors after the unknown, we spend a lot of our lives pacing that windswept perimeter: We take drugs; we go to circuses; we tramp through jungles; we listen to loud music; we purchase exotic fragrances; we pay hugely for culinary novelties, and are even willing to risk our lives to sample a new taste. In Japan, chefs offer the flesh of the puffer fish, or fugu, which is highly poisonous unless prepared with exquisite care. The most distinguished chefs leave just enough of the poison in the flesh to make the diners' lips tingle, so that they know how close they are coming to their mortality.
Deep down, we know our devotion to reality is just a marriage of convenience, and we leave it to the seers, the shamans, the ascetics, the religious teachers, the artists among us to reach a higher state of awareness, from which they transcend our rigorous but routinely analyzing senses and become closer to the raw experience of nature that pours into the unconscious, the world of dreams, the source of myth.
Our several senses, which feel so personal and impromptu, and seem at times to divorce us from other people, reach far beyond us. They're an extension of the genetic chain that connects us to everyone who has ever lived; they bind us to other people and to animals, across time and country and happenstance. They bridge the personal and the impersonal, the one private soul with its many relatives, the individual with the universe, all of life on Earth. In REM sleep, our brain waves range between eight and thirteen hertz, a frequency at which flickering light can trigger epileptic seizures. The tremulous earth quivers gently at around ten hertz. So, in our deepest sleep, we enter synchrony with the trembling of the earth. Dreaming, we become the Earth's dream."
