Generally, all chiroprators are holistic. The popularity of chiropractors today, is largely based on the idea that we provide an effective, holistic option to people who don't wish to follow the path of conventional medicine.
Caycean Chiropractic as I have described it, involves two concepts. First, it must be understood that all the functions of the body are controlled by nerve impulses from the brain. These impulses travel from the brain, down the spinal cord and to the respective organ, tissue, bones, muscles (everything). If these impulses are blocked by spinal vertebrae (that the nerve has to travel through to get to its destination), which has frequently moved out of place, then the signal is interrupted and the organ doesn't receive the necessary nerve energy. This leads to system dysfunction.
Edgar Cayce made healing suggestions to tens of thousands of people and in almost every case, spinal correction was suggested to allow the body to heal and recover much faster. It should be noted that this concept describes how certain levels of the spine directly control or inhibit certain organ systems. This concept of Caycean Chiropractic is an old chiropractic teaching also.
The second level of Caycean Chiropractic involves balance of the body, mind and Spirit. This is accomplished through different techniques. The objective is to allow healing energy, which originates in the Soul of the individual's mentality and thought and is then manifested throughout a person's physical body. Establishing a connection to the Universal energies and keeping a positive mental attitude have been proven to be body healing accelerators.
