A fool and his money are soon invited everywhere.

The fool has one great advantage over a man of sense; he is always satisfied with himself.

The man who remains a fool even in advanced age is really a fool, just as the Indra-Varuna fruit does not become sweet no matter how ripe it might become.

Do not keep company with a fool for as we can see he is a two-legged beast. Like an unseen thorn he pierces the heart with his sharp words.

The tongue of a fool is the key of his counsel, which, in a wise man, wisdom hath in keeping.

Never argue with a fool, onlookers may not be able to tell the difference.
