B.J. Palmer writes: "We chiropractors work with the subtle substance of the soul. We release the prisoned impulses, a tiny rivulet of force, that emanates from the mind and flows over the nerves to the cells and stirs them to life. We deal with the magic power that transforms common food into living, loving, thinking clay; that robes the earth with beauty, and hues and scents the flowers with the glory of the air.
In the dim, dark distant long ago, when the sun first bowed to the morning star, this power spoke and there was life, it quickened the slime of the sea and the dust of the earth and drove the cell to union with its fellows in countless living forms. Through eons of time it finned the fish and winged the bird and fanged the beast. Endlessly it worked, evolving its forms until it produced the crowning glory of them all. With tireless energy it blows the bubble of each individual life and then silently, relentlessly dissolves the form and absorbs the spirit into itself again."
Wikipedia defines Chiropractic as follows:
"Chiropractic (from Greek chiros and praktikos meaning "done by hand") is a health care profession whose purpose is to diagnose and treat mechanical disorders of the spine and musculoskeletal system with the intention of affecting the nervous system and improving health. It is based on the premise that a spinal joint dysfunction can interfere with the nervous system and result in many different conditions of diminished health. While some chiropractors use the term vertebral subluxation to describe what they treat, others have dropped this concept and concentrate mostly on the musculoskeletal components of spinal injury and rehabilitation of the spine. In contrast, the term subluxation as used in conventional medicine is usually associated with specific conditions which are a direct consequence of injury to joints or associated nerves."
Most structural spinal disorders are due to the neglect of strains, minor falls and accidents that disturb the delicate balance of one or more of the many irregular joint surfaces within the spinal system. The neglect of vertebral balance renders the musculoskeletal system liable to further injury and eventual degenerative disorders.
