Emotions arise when a being has sufficiently complex thought, and thus the heart is an emergent phenomenon of the mind. There are four recognised primary emotions, each of which has a positive and negative aspect.
A heart in balance is said to be happy.
These emotions affect each other as their corresponding substances do:
- dread blocks melancholy,
- melancholy evaporates complacence,
- complacence quenches passion,
- passion burns dread.
- caution blocks misery,
- misery evaporates joy,
- joy quenches anger,
- anger burns caution.
