The Spirits' Book
Book Two - The Spirit World
Chapter VI - Spirit Life
231. Are errant spirits happy or unhappy?
“It depends on their merit. They suffer from the passions they have retained, and are more or less happy depending on the strength of their connection to material life. When a spirit is in an errant state, it has perceptions of what it needs in order to be happy. When this happens, it is compelled to seek what it lacks. However, a spirit is not always permitted to reincarnate when it desires to do so, and in that case it becomes a punishment.”
