Your heart produces an electromagnetic field 5000 times as powerful as that produced by your brain.[1] This field projects from your physical body to contribute to the circumvent field or aura. 60–65 % of heart cells are neural cells connected to the central nervous system and brain and concomitant with the amygdala, thalamus, hippocampus and cortex.[2]
One way the heart communicates with the brain and the rest of the body is ‘energetically’. If the electromagnetic energetics of the heart are altered so are the resultant communication signals. In fact, heart transplant recipients often show a different personality post-operation, literally having a ‘change in heart’.
