Beware lest you lose the substance by grasping at the shadow.
Give assistance, not advice, in a crisis.
A Fox entered the house of an actor and, rummaging through all his properties, came upon a Mask, an admirable imitation of a human head. He placed his paws on it and said, "What a beautiful head! Yet it is of no value, as it entirely lacks brains."
It is foolish to try to imitate the skills of others.
Fine clothes may disguise, but silly words will disclose a fool
Faithful are the wounds of a friend; but the kisses of an enemy are deceitful.
