The heart is as a globe covering the light of the soul, and its different emotions are different colors of this globe. Every emotion is produced by a certain element. While experiencing life through the heart, the soul at that moment thinks: I am sad, or glad, or afraid, or humorous. In fact it is its momentary experience. When the influence of a particular element is changed the emotion has expired and the soul is as pure as it was before. Nothing touches it. It is pure by nature and it always remains pure. If ten people in turn look in a mirror, the mirror shows everyone his face reflected in it and it is clear enough to take every other reflection. In the end the mirror is as clear as before; no face that has ever been reflected in it has left an impression on it.

There are nine different emotions which the soul experiences through the heart, and these are influenced by corresponding elements, thus:

Emotions Elements
Humor Air
Joy Ether
Sorrow Earth
Fear Ether and Air
Pity Water
Courage Fire and Air
Indifference Ether, Fire, and Earth
Passion Fire
Anger Fire and Air
