Take care what you say before a wall, as you cannot tell who may be behind it

A scholar without diligence is a lover without money

O wise man, wash your hands of that friend who associates with your enemies

However much you are read in theory, if thou hast no practice thou art ignorant

The rose and the thorn, and sorrow and gladness are linked together

If, of thy mortal goods, thou art bereft, And from thy slender store two loaves alone to thee are left, Sell one and from the dole, Buy Hyacinths to feed the soul
