The Heart is the Horizon.

It is written that the heart of a fool is on the left side of the chest; the heart of a wise man (or woman) is on the right side of the chest.This means we have a spiritual heart next to having a fysical heart.This is often forgotten by a sentimental, materialistic approach of the heart, overburdening the fysical and ridiculing the spiritual heart (often used as a metaphor of the capacity of love) that way.
