motive, the attainment of which will give them personal pleasure. They are fired by an impulse of soul that boils with an inward flame and urges them onward, regardless of the outer mind of caution and conservatism.

The trait of man named variously zeal, enthusiasm, intensity of soul, is a prime faculty of spiritual man. It is found in one of the disciples of the type man Jesus, and its character is revealed in his name, Simon the Zealot.

Zeal's throne or center of activity in the body is at the base of the brain, in the medulla. It is the seat of the animal soul, and its office is to vaporize the fine nerve fluid and distribute it to the senses. The medulla performs in the body the work of the carburetor in a motorcar.

An intense desire to carry out some idea forces the nerve fluid into the medulla, where it is atomized with inspiration (air) and then flared through the optic nerve to the eye, where the Spirit ignites it, and it flashes into light. "It is the Spirit that giveth life."

When the Spirit moves a man from within to the accomplishment of some cherished ideal and the intellect steps in and says it can't be done, a conflict ensues and the natural flow of the volatile body is impeded. Congestions and clots form in the circulation, the man gradually slows down, and what are called the marks of old age appear. This is why man should never give up the quest for greater and better expression of God-given abilities.
