“There is a kind of person whose mouth never seems to stop moving, and everything they say is hurtful and malicious. They take pleasure in harming others by spreading gossip and rumors, which eventually causes great trouble.”

White Tara continued:

“When one harms others with speech, that is poisonous speech. In future lives, such people will fall into the three lower realms and be reborn as venomous snakes. If they fall into the lower realms, they may also become venomous beasts, venomous birds, or other venomous creatures. Even if they are reborn as humans, they will still argue endlessly and delight in deception.”
