Confide not to a friend every secret thou possessest. How knowest thou that he will not some time become thy foe? Inflict not every injury thou canst upon an enemy because it is possible that one day he may become thy friend.
Reveal not thy secret to any man although he may be trustworthy, because no one can keep thy secret better than thyself.
Silence is preferable than to tell thy mind To anyone; saying what is to remain unsaid. O simpleton, stop the source of the spring. When it becomes full, the brook cannot be stopped.
