The heart, “through insight and understanding,” rules the energetic and physical organism of human beings, as well as their social relationships. Its main function is the capacity for resonance.
That means that the heart enables the different parts of a person to step into resonance with each other, and, through this, to form a lively organism. It enables the whole person to be in resonance and integrate with his environment.
Resonance means reciprocal vibration. It means understanding through empathy. ”A healthy heart gives one the courage to be aware of the ‘vibrations’ of other people and situations….” (from: W. Rappenecker – Five Elements and Twelve Meridians)
