Just look at the ruthlessness of Yin Law.
"There is an evil mirror in hell, which can also be called an industry mirror. Its working principle is nothing more than a huge projection screen, which connects the images of good and evil recorded in our knowledge field to the big screen for playback.
Master, does black and white impermanence really write down people's hearts to discuss merits and demerits? Thank you very much for answering many questions! Actually, it can't be called black and white impermanence. Black and white impermanence is the staff of the underworld, which is different from following everyone's merits and demerits. Merits and demerits: God is with everyone, and the smallest good thoughts and evil thoughts are recorded one by one. Those who remember goodness are called gods of the same name, white and male; Those who remember evil are called the same gods, black women, and those who have feelings can see them. ?
