When you set sail for Ithaca,
wish for the road to be long,
full of adventures, full of knowledge.
The Lestrygonians and the Cyclopes,
an angry Poseidon — do not fear.
You will never find such on your path,
if your thoughts remain lofty, and your spirit
and body are touched by a fine emotion.
The Lestrygonians and the Cyclopes,
a savage Poseidon you will not encounter,
if you do not carry them within your spirit,
if your spirit does not place them before you.
