All laws, nothing, are empty after all. What do you mean?

It means that all things, such as form, essence and all magic, really don't necessarily exist. The expression of all meanings is only an illusion, which cannot be touched and explained. There is no need to pursue excessive material life. Your carefree happiness is detached, and you are desperately pursuing it. Just empty. Happiness lies in contentment, and seeing through the world is the highest state.
