this body is but a bio-chemical machine

We always hear how the body is like a car and the soul its driver. In fact,there is a verse in the Gita that reflects this idea

The Supreme Lord is situated in everyone's heart, O Arjuna, and is directing the wanderings of all living entities, who are seated as on a machine, made of the material energy. – BG 18.61

I was reading a book on medical resuscitation and how they bring the dead back to life. The book, in one part, talks about the human body. Below is the excerpt;

The human body is an incredibly complex machine composed of different components, each with a specific role that enables this machine to function. Like all machines, the body needs fuel to produce energy, which it uses to sustain its biological activities, also known as metabolism. This fuel comes in the form of the foods we eat, but the food alone does not sustain us. Once consumed, these raw products must be burned and converted into energy. This combustion process requires a constant supply of oxygen, the same an engine needs a mixture of oxygen and fuel to combust. The fuel in the engine is supplied through a gas tank while the oxygen is injected through vents and in both cases, when they meet, combustion takes place. This creates the energy that enables the other components, such as the wheels, power steering, and lights, to function, but the combustion process also produces waste products. In a car, the waste products are pushed out the through the exhaust system; in the body the gastrointestinal track functions like the gas tank, taking in food that comes from the stomach, while oxygen is supplied through the lungs acting as massive vents. This entire process in both the car and our body is stimulated by the intake of oxygen. Thus, like a car,if our activity revs up as we run, we need far higher levels of oxygen in order to burn more fuel and keeps the cells and organs working .- By Dr. Sam Parnia, M.D. from the book Erasing Death, page 37-38

The author (lead of the AWARE study) categorically explains how the body is but a machine. The next natural question is - who drives the machine (the body), we get the answer in the Bhagavad Gita –the soul.
