I’ve been thinking a lot of the parallelism between the physical heart and the figurative heart. Our physical hearts are enclosed in a double-walled sac for protection, to anchor its surrounding structures and prevent blood from overfilling it. When we first meet people our figurative hearts are completely covered, “which protects the heart from any kind of external jerk or shock”, double-walled against anything emotionally harmful.
After the first few introductions most people make it to our outer wall, which is the first of three layers of the heart. This is yet another protective layer to our hearts, filtering first impressions and smoothing the way for the safe ones to enter the second layer; this is where we keep our acquaintances.
The middle layer is comprised of cardiac muscle that is highly resistant to fatigue, though it works constantly. When people reach the middle layer of our hearts they’ve reached the point where we’ve chosen to love them, and to work at the friendship consistently without growing tired of another’s shenanigans. The middle layer is also responsible for propelling blood into the rest of the body; the same as how this middle layer of our figurative heart causes our love to grow and spread throughout our feelings and our actions, because without this middle layer we would have no cause to move unselfishly. Therefore this middle layer is where we learn to care for each other and work through our issues together, still without entirely letting one another in.
The inner layer of the heart, the endocardium, is the last layer in the heart that is so deep that it actually lines the inner chamber of the heart. The function of the endocardium is to control the myocardium (middle layer of the heart) from the safety of the inner chamber. People who’ve entered into the middle layer of our hearts only did so with the authorization, however unnoticed, of the deepest layer of our heart. This inner layer merges with the absolute inner workings of the heart.
The heart is life to the entire body, without out it we would die. The thing about the heart is that it can only discharge what it has received. The blood that is pumped into it through each of these layers and various security checkpoints is then filtered, oxygenated and pumped out into the rest of the body. This is what gives life, the oxygen rich blood being sent out into the rest of the body.
Our figurative hearts give life to our souls, allowing us to live a life of love, because what would life be without love? Ultimately, we have all these walls and protective layers about our hearts because we are afraid of losing, or damaging them. And whether we like it or not once we let people past our initial protective layers and into the middle of our hearts, they will seep into the depths of our hearts to be loved unconditionally. Even when we’re hurt our hearts will insist on working at the wound and healing it. Guarding your heart becomes increasingly important as you realize that whatever you allow in, as sure as your heart beats, it will be sent out into the rest of your body, seeping through your injuries. Meaning, when you hold onto to hurt, anger, bitterness, etc. you are poisoning the very blood that pumps through your veins, harming not only the person whom you hold these things against, but also your own flesh, body and life; and it will come out in the worst way, if and when you are pricked again. When there is an infirmity in the heart the middle layer and the inner layer work together to heal it, for the health of the body; because a healthy heart will function at it’s total capacity bringing life to the blood that is sent out to every part of the body, which, in turn makes the person more resilient against the inevitable anguishes of life. And that is why taking care of both of our hearts is so crucial to our existence.
My son, give attention to my words; incline your ear to my sayings. Do not let them depart from your eyes; keep them in the midst of your heart; for they are life to those who find them, and health to all their flesh. Keep your heart with all diligence, for out of it springs the issues of life. -Proverbs 4:20-23
