Music is a fantastic peacekeeper of the world, it is integral to harmony, and it is a required fundamental of human emotion.

When a man sees something desirable, he must reflect on the fact that with time it could come to involve what is detestable. When he sees something that is beneficial, he should reflect that sooner or later it, too, could come to involve harm.

If the blood humor is too strong and robust, calm it with balance and harmony.
