The Electromagnetic Heart
The Teaching
The heart generates the largest electromagnetic field in the body. The electrical field as measured in an electrocardiogram (ECG) is about 60 times greater in amplitude than the brain waves recorded in an electroencephalogram (EEG).
The heart's electromagnetic field becomes more organised during positive emotional states. When people touch or are in proximity, a transference of the electromagnetic energy produced by the heart occurs. One person's ECG signal is registered in the other person's brainwaves.
The electromagnetic field of a person experiencing strong emotions can influence the heart rhythms and brain states of those nearby — a phenomenon researchers call energetic entrainment.
The heart's electromagnetic field can be detected by other individuals and can produce measurable effects in a person five feet away.
Commentary
The emotional energy that highly sensitive people have always described sensing in others turns out to have a precise physical substrate. The heart's electromagnetic field radiates outward, measurable, quantifiable, and variable depending on the emotional state of the person producing it.
During anger or anxiety, the field becomes chaotic and disordered. During love, appreciation, or calm, it becomes coherent, organised and rhythmic. These patterns are broadcast into the surrounding environment and registered in the nervous systems of nearby people before conscious thought has had time to process them.
The HeartMath research did not discover something new. It measured something ancient. The transmission of emotional energy between people has been observed, worked with, and built around by healers and contemplatives across every tradition on this map. What changed is that we now have the instruments to see it.
The Hermetic teaching 'as above, so below' is self-similar across scale: the same electromagnetic field that carries emotional information between individuals is structurally similar to the field that carries information between neurons within a single nervous system. This is Indra's Net made electromagnetic, each node simultaneously broadcasting and receiving the state of every other node.
