Repentance guides the direction of the thoughts in the heart, and can glimpse the past of a thousand years and the dawn of five hundred years.
Cultivation is for the purpose of immortality, and to urge repentance is to ensure death. Even if you can predict the future, so what if you can't tell the truth? It's like having an erotic dream, just to know what the answer is that you would rather sacrifice your life for, or to be happy in the dream for a few seconds to comfort the regrets in your heart?
Whether it's worth it or not, only ghosts know, because everyone who knows is already dead.
