The tongue must be sanctified by the repetition of the name. It has also to use sweet expressions which will spread contentment and joy. Be very careful about your speech. Animals have horns, insects have stings, beasts have claws and fangs. But, man's biggest weapon of offence is his tongue. The wounds that his tongue inflicts can scarce be healed; they fester in the heart for long. They are capable of more damage than even an atom bomb.
- Divine Discourse, July 29, 1964.
