Don't tell lies. Don't be catty, malicious, vicious, slanderous or libelous in your conversation. Don't delight in salacious rumor-mongering. Why? Because these things bring about disharmony in your relationships with people. When you speak in these ways with others rather than truthfully and down-to-earth, it sets up a relationship between you and other people that's based on untruths. You may be in control of these untruths at first, but eventually, they take on a life of their own, and you'll start to get caught in your own web of deception and mean-spiritedness. Stay away from harsh and malicious language. Foaming at the mouth is to be avoided. Speak carefully and appropriately. Ethical conduct is based on Right Speech.
