Friendship is one soul in two bodies.
You should make great things, not promising great things.
If you're asked: What is the silence? Respond: It is the first stone of the Wisdom's temple.
Concern should drive us into action and not into a depression. No man is free who cannot control himself.
A blow from your friend is better than a kiss from your enemy.
When the wise man opens his mouth, the beauties of his soul present themselves to the view, like the statues in a temple.
