It's not a poem but an extract from the book "Wuthering Heights".
I'm sorry, I'm a native speaker, not a learner. I know hundreds of songs and dozens of poems.
When we see the first star at night, we say a little rhyme I learned as a child:
Star light, star bright,
First star I see tonight,
I wish I may, I wish I might
Have the wish I wish tonight!
One of the most haunting songs I know is "How Deep is the Ocean," by the US songwriter Irving Berlin. It was written in 1932. The most famous recording of it is by Bing Crosby:

How much do I love you? I'll tell you no lie:
How deep is the ocean? How high is the sky?
How many times a day do I think of you?
How many roses are sprinkled with dew?
How far would I travel to be where you are?
How far is the journey from here to a star?
And if I ever lost you, how much would I cry?
How deep is the ocean? How high is sky?
This is one of the most poetic songs in the English language and still today the meaning is VERY vague, but it's beautiful. Leonard Cohen's "Hallelujah"
Now I've heard there was a secret chord
That David played, and it pleased the Lord
But you don't really care for music, do you?
It goes like this, the fourth, the fifth
The minor fall, the major lift
The baffled king composing Hallelujah
Hallelujah, Hallelujah
Hallelujah, Hallelujah
Your faith was strong but you needed proof
You saw her bathing on the roof
Her beauty and the moonlight overthrew you
She tied you to a kitchen chair
She broke your throne, and she cut your hair
And from your lips she drew the Hallelujah
Hallelujah, Hallelujah
Hallelujah, Hallelujah
You say I took the name in vain
I don't even know the name
But if I did—well, really—what's it to you?
There's a blaze of light in every word
It doesn't matter which you heard
The holy or the broken Hallelujah
Hallelujah, Hallelujah
Hallelujah, Hallelujah
I did my best, it wasn't much
I couldn't feel, so I tried to touch
I've told the truth, I didn't come to fool you
And even though it all went wrong
I'll stand before the Lord of Song
With nothing on my tongue but Hallelujah
Hallelujah, Hallelujah
Hallelujah, Hallelujah
Mikkel, if you still need an explanation for
"Or who is
he so fond will be the tomb
Of his self-love, to stop posterity?"
It's wordplay, and has two viable meanings:
1. "fond"=stupid. Who is so stupid that he would stop his own posterity, and thereby destroy himself? Even if you don't like kids, you still probably like yourself, so your self-love should drive you to reproduce.
2. Shakespeare is speaking of himself instead of his lover. Yes Shakespeare loves him and will be jealous of the woman he joins with, but he does not want to cause the extinction of the person he loves by preventing him from procreating.
Personally, I recommend "Kubla Khan". It has a great rhythm that can drive you forward if you recite it in the middle of a long walk.
