La idealoj, kiuj lumigis mian vojon kaj donigis unu kaj pluan fojon, novan kuraĝon por fronti la vivon, estis, boneco, beleco kaj vero.
Los ideales que han iluminado mi camino y han proporcionado una y otra vez nuevo valor para afrontar la vida han sido: la bondad, la belleza y la verdad.
The ideals that have lighted my way, and time after time have given me courage to face life cheerfully have been kindness, beauty and truth.
