Need with poetry

do not go gentle into that good night,
old age should burn and rave at close of day;
rage, rage against the dying of the light.

though wise men at their end know dark is right,
because their words had forked no lightning they
do not go gentle into that good night.

good men, the last wave by, crying how bright
their frail deeds might have danced in a green bay,
rage, rage against the dying of the light.

wild men who caught and sang the sun in flight,
and learn, too late, they grieved it on its way,
do not go gentle into that good night.

grave men, near death, who see with blinding sight
blind eyes could blaze like meteors and be gay,
rage, rage against the dying of the light.

the word rage can mean “anger,” but it can also mean “passion”—an outpouring of feeling. how might thomas have been using both meanings in the poem?
