The food a person consumes, does not provide the totality of the Human Body’s Energy requirements.
The food a person consumes, drives the primary process which taps into the infinite pool of “Life Force”, and that draws in the predominant Energy the Human Body utilises.
The fundamental mechanism for this process is the Biological Nervous System. Or more specifically, the Synapses which constitute a Biological Nervous System.
A Synapse is made up of what is referred to as a Presynaptic Neuron and a Postsynaptic Neuron with a small Synaptic gap in between.
As a Synapse fires, it creates an Ethereal vacuum, which Life Force is then drawn into.
Due to the fact that each individual Synapse and the Energy required to fire, is so small, the Life Force that is dawn, is also small.
However, when there are trillions of Synapses firing constantly in the Human Body throughout the day, the Life Force or Energy draw, is substantial.
Physical movement, especially during high intensity exercise, is when muscle Synapses are most active. But, with the brain composed of the highest concentration of Synapses, Brain function is by far the greatest contributor to Life Force reception. Provided there is any real meaningful Brain activity occurring.
Meaningful Brain activity comes about from active cognitive participation, not from passive stupification in the form of such things as mindless entertainment.
With regard to the food component, not all food is equivalent in this process. Healthy, high quality foods facilitate the process. While unhealthy, poor quality foods inhibit the process.
Mechanical Energy equations are not relevant to Biological systems, when there is no understanding of the underlying Cosmic Energy interactions with Biological systems.
