Answer: In our world all four spiritual covenants are very complex and special laws.
The covenant of the tongue means that a person should be careful not to harm any creations with one’s words, not with thoughts as in the first three laws, but precisely with words, with expressing oneself.
When a person works for bestowal and for connection, then one must perceive the whole world as perfect not only with respect to one’s friends, but with respect to other people and even animals. Therefore, we cannot issue critical remarks about anyone. You perceive the whole world as an act of the Creator and you refrain from causing verbal or mental harm to any of His creations.
