Previous lives were fairy girls in the sky. Why did she come to the human world in 1990?

Fairy girls in heaven are all beings in heaven. When she enjoys all the blessings, she will be dragged by her own karma and reborn to the other six paths. It is lucky to be reincarnated as a human being. Many people are in pain after enjoying all the blessings, such as hell as an arrow. The six divisions of the wheel of karma are tragic. If you want to get rid of it at last, you must study Buddhism diligently. There is no other way.
