A very reasonable statement:
"As long as you find that this person's nature is not right, do not talk to them, not a word should be said, just let it go, leave it to karma."
There is no need to argue with people who have a misaligned perception, and even less to entangle with those whose nature is distorted.
Good and evil have their own heavenly cycle, you only need to maintain your own rhythm, do not let bad people and bad things dirty your circle, disrupt your life.
