A word is an action.
Do not say words you do not feel, lest your soul be blackened with darkness.
— From the Book of Divine Thoughts
Your enemies can be more useful to you than your friends, because your friends can often pardon your weaknesses, but your enemies notice them and attract your attention to them.
Do not neglect the opinion of your enemies.
A wise man does not judge a person for his words, but at the same time does not neglect another person’s words, even when these words are pronounced by an unworthy person.
— Chinese Wisdom
A person’s tongue is a tool which is sufficient to transmit the ideas created by the human mind. But in the domain of true and deep feelings, our tongue is weak.
— Lajos Kossuth
Never is there a single instance when a lie can be justified.
