It is extremely sad to be separated from heaven and man on the wedding night, and it is even more painful to travel to another time and space. I originally wanted to stand by and watch life and death go by, but in the end I could not escape the arrangement of fate. I threw myself into the world of mortals and endured the suffering of reincarnation. I was willing to live forever without being able to escape.
There is a saying in the Buddhist scriptures: If love is not heavy, Shapo will not be born.
Sha Po is the world of mortals.
