<span>Desiderata.....a beautiful piece. Like all poetry, it's there for you to take away what you can use. You do not have to agree with every word. Yes, there are problems..he does not fudge that fact, but he offers some hope and personal transformations to consider... </span>
Depending on where you are brought up, and the difference in society, you will see different things and people will have different beliefs in symbolism. For example, seeing a bird in a picture for a Christian may represent a dove and be seen as peace, but for someone else it may be seen as a vulture and represent death
The theme of poetry is what happens in a poem, or B. the underlying message that a poem conveys.
A and C refer to rhymes and meters, which have nothing to do with the theme.
D refers to genres, not themes.
