May 12:

May 12th. In the natural world it only requires a single vital correspondence of the body to be out of order to ensure Death. It is not necessary to have consumption, diabetes, and an aneurism to bring the body to the grave, if it have heart disease. He who is fatally diseased in one organ necessarily pays the penalty with his life, though all the others be in perfect health. And such, likewise, are the mysterious unity and correlation of functions in the spiritual organism that the disease of one member may involve the ruin of the whole. Natural Law, Mortification, p.187.
