If you ever wondered from where the expression mens sana in corpore sano is, here is the answer:
Orandum est ut sit mens sana in corpore sano.fortem posce animum mortis terrore carentem,qui spatium uitae extremum inter munera ponatnaturae, qui ferre queat quoscumque labores,nesciat irasci, cupiat nihil et potioresHerculis aerumnas credat saeuosque laboreset uenere et cenis et pluma Sardanapalli.monstro quod ipse tibi possis dare; semita certetranquillae per uirtutem patet unica uitae.
Satire X: Wrong Desire is the Source of Suffering, the Satires are a collection of satirical poems by the Latin author Juvenal written in the late 1st and early 2nd centuries AD.
It is to be prayed that the mind be sound in a sound body. Ask for a brave soul that lacks the fear of death,which places the length of life last among nature’s blessings,which is able to bear whatever kind of sufferings,does not know anger, lusts for nothing and believes the hardships and savage labors of Hercules better thanthe satisfactions, feasts, and feather bed of an Eastern king.I will reveal what you are able to give yourself;For certain, the one footpath of a tranquil life lies through virtue.
When in doubt, the poetry can save you.
