Actually, the whole sentence is Orandum est ut sit mens sana in corpore sano.: "You should pray for a healthy mind in a healthy body."

Juvenal, in his Satires, suggests to us that we must pray for attainment of mens sana in corpore sano, and his phrase has found use for many centuries as the stated educational goal of many schools: "To train the body as well as the mind."

Public statements by some near-illiterate college athletes suggest that the sound body is too often achieved without accompanying improvement of the mind.
