This lot has the meaning of "storing a sword in laughter". It admonishes the parties involved not to harbor evil plans in their hearts. Language is both an art and a tool, used to kill and to save. Some are glib and say words in a roundabout way, making others believe them deeply on the spot. While it is good to speak the truth, it is also important to "think with the heart" when you speak. If you have good thoughts, the words that come out of your mouth will also be good words. On the other hand, if the heart is filled with resentment and thoughts of retaliation, language becomes a terrible tool that harms people without form. Know that if you harbor ill will, you will eventually harm others and harm yourself.
