Where I am from, there are many different sorts of spirits, most notably elemental spirits. There are spirits of nature, which are the will of the planet. But there are ones that are the elemental force of humanity itself, those who accomplished great deeds during their lifetime and were revered after their death. As I understand it, the hopes and wishes of mankind create a sort of receptacle for this force, and the spirit becomes what is called a Heroic Spirit.

Though, I have to admit that I am an exception to this rule. I had made a contract with the world to become a Heroic Spirit, so I had not yet died before I became one.

But what this means beyond this is that as long as humankind is what it is, that need will always be present.
