Which of its many definitions is uppermost in your thought when you see the word "heart"? Do you think of the human heart as giving life or as taking life away by its action or inaction?
In Christian Science we learn that man's life is spiritual, the reflection of the one Life, God. Hence man's true life is never in a human heart and cannot be affected by the action or inaction of the heart. Mankind often find this difficult to understand. Through Christian Science we learn that the action of the human heart is controlled in just the same way that the movement of the human hand or leg is controlled, not by matter, but by so-called mortal mind. And the carnal or mortal mind has nothing to do with man's true life.
Mary Baker Eddy writes in "Science and Health with Key to the Scriptures" (p. 187), "The valves of the heart, opening and closing for the passage of the blood, obey the mandate of mortal mind as directly as does the hand, admittedly moved by the will." Then follows on page 191 this important counsel: "The human thought must free itself from self-imposed materiality and bondage. It should no longer ask of the head, heart, or lungs: What are man's prospects for life?"
