Letters 10.4

Speak, and live, in this way; see to it that nothing keeps you down. As for your former prayers, you may dispense the gods from answering them; offer new prayers; pray for a sound mind and for good health, first of soul and then of body. And of course you should offer those prayers frequently. Call boldly upon God; you will not be asking him for that which belongs to another.
