Spirits during Wars
547. Do spirits who fought opposing side of each other during battle still see each other as enemies after they die? Are they still furious with one another?
“Under such circumstances, a spirit is never calm. At first, it may feel enraged with its enemy and even pursue it. When it has recovered its composure, it sees that its animosity is fruitless. Nonetheless, it may retain some traces of it for a longer or shorter period of time, depending on its character.”
