Vital Energy Imparted to Mind Through Brain—The Lord would have our minds clear and sharp, able to see points in His word and service, doing His will, depending upon His grace, bringing into His work a clear conscience and a thankful mind. This kind of joy promotes the circulation of the blood. Vital energy is imparted to the mind through the brain; therefore the brain should never be dulled by the use of narcotics or excited by the use of stimulants. Brain, bone, and muscle are to be brought into harmonious action that all may work as well-regulated machines, each part acting in harmony, not one being overtaxed.—Letter 100, 1898.
