The central point of our bodies is the heart. In the ancient teachings of Aristotle the heart was regarded as the true seat of intelligence.For the Alchemists, the heart was the image of the sun within man. The importance of love in the mystic doctrine of unity explains how it is that love symbolism came to be closely linked with the heart symbolism, for to love is only to experience a force which urges the lover toward a given centre. That said: The Heart signifies love as the centre of illumination and happiness.
