English Literature. John Donne's "The Sun is Rising"

Busy old fool, unruly Sun,
Why dost thou thus,
Through windows, and through curtains, call on
us?
Must to thy motions lovers' seasons run?
Saucy pedantic wretch, go chide
Late schoolboys, and sour prentices,
Go tell court-huntsmen that the king will ride,
Call country ants to harvest offices,
Love, all alike, no season knows, nor clime,
Nor hours, days, months, which are the rags of
time.

Thy beams, so reverend and strong
Why shouldst thou think?
I could eclipse and cloud them with a wink,
But that I would not lose her sight so long:
If her eyes have not blinded thine,
Look, and tomorrow late, tell me
Whether both the'Indias of spice and mine
Be where thou leftst them, or lie here with me.
Ask for those kings whom thou saw'st yesterday,
And thou shalt hear: 'All here in one bed lay.'

She'is all states, and all princes I,
Nothing else is.
Princes do but play us; compar'd to this,
All honour's mimic, all wealth alchemy.
Thou, sun, art half as happy'as we,
In that the world's contracted thus;
Thine age asks ease, and since thy duties be
To warm the world, that's done in warming us.
Shine here to us, and thou art everywhere;This bed thy centre is, these walls, thy sphere.

The tone of this beautiful poem is like a prayer, speaker is a lyrical subject. At the very beginning of the poem there's an apostrophe, direct address to God and the Sun. Poem is filled with lots of conceits, John Donne is not very outstanding poet, reading his poems we have to imagine what he tries to convey, imagination is a key to understand his means of perception.  

According to William Blake "... The world of eternity is a world of Imagination ..."

The setting of the poem is Home, which for everyone is understood as safe harbor. The poem describes two subjects a man and a woman, the sun rising up, wakes them and intrudes their intimacy, dream, morning, the Sun is not welcome, it is an intruder. 

The Sun is rising, there's a time to start a day, to wake up, to make decision, to live. The couple of lovers want to be left alone, they do need the "rude"Sun to spoil their morning. They whisper, giving warning to the Sun; 

"...Go tell court-huntsmen that the king will ride..."  

They say, simply, go away to the Royal Chamber and  disturb there, we do not want you, Sun, leave Us alone. 

We do need and want to keep Our privacy, the couple of 

lovers feels a bit ashamed and feel a kind of discomfort. The couple believe the times they are sharing together will last as long as they live. Their and Our life can be describes as "Rag of Time". The title does have a double meaning, The Sun is The Son - the son of God who symbolizes a new era, a new life. 

The title has also go a scientific meaning, the astronomical development from Galileo to Copernicus revolutionized the way of perceiving the Earth and the Sun. The Earth is no longer in the center of the Universe,  the Sun is. The Sun is the focal point, unquestionably.

At the end of the poem the couple forgive the Sun its intrusion, in contrary, the lovers are happy, namely, the sun warms them up, they look at the Sun and see it in the center of the Universe.
