The Purple Sage does not need to do anything and does not need self-certification. It is a shining example of governing by inaction and being a monarch at ease. Because people can't help themselves in the Jianghu, it is inevitable to bear the cause and effect, and they can't be blamed for doing well. It is difficult for anyone to let others recognize his own proof, but if he has to prove himself, it is: he is always there, he is always at ease, he is omniscient and omnipotent, and he is all wise and wise.
In this way, it is not the Purple Sage who does things and proves himself, and these things are handed over to human beings, or people want to do things without bearing the evil consequences, and ask the Purple Sage for friendly help. People want to prove their innocence omnipotent, and pray for the purple saint to show magical power.
