Life is a Triune having three necessary united factors namely, intelligence, force, and matter.
Without intelligence, matter could not even exist. Without matter, intelligence could not be expressed. Then there is a bond between intelligence and matter that cannot be dispensed with. These three factors; intelligence, matter, and the bond between them, are inseparable. The bond is called force. It is sometimes called " The Missing Link." Unlike other sciences, which study them separately, Chiropractic studies them all together.
