The Electromagnetic Field of The Heart
Every heart generates a rhythmic electromagnetic field. In fact, the heart generates the strongest rhythmic electromagnetic field in the body. Measured by scientific devices, the heart's electromagnetic field is approximately five thousand times greater in strength than the field produced by the brain.
The heart's field permeates every cell in the body and radiates up to eight feet outside the body. It theoretically travels even further, although its field strength becomes too low for us to measure beyond this.
The heart is the primary regulator and transmitter of emotions in the human body. Studies have found that our emotions are reflected in the patterns of our heart rhythms. These changing rhythms modulate the field produced by the heart (similar to how a radio wave is modulated so that the music can be broadcast) and in doing so, communicate emotional information that other electromagnetic fields are able to receive and recognize.
Communication between the heart and brain is a dynamic, ongoing, two-way dialogue, with each organ continuously influencing the other’s function. The brain and the heart also share about 60% of the same type of cells. In early Buddhist text, there is a word "citta", which refers to the subjective "heart-mind" consciousness.
Keeping your thoughts clear, positive, and compassionate will contribute to a healthier heart and a healthier, more harmonious electromagnetic signal. Likewise, keeping the heart center awake and vibrant will help bring about a healthier, more peaceful, open mind.
