The alliteration in these lines steals over the reader’s sensation like a sweet slumber

Surpassingly; beyond

I could have sworn they were cousins…

Shelley is like a wind instrument, waiting to be animated by the breath of Nature’s inspiration

The night is quite resourceful, and can make something out of nothing

A fancy/silly word for “gift”

Nature has a great sense of economy: if you don’t have much going for you, a hefty dose of pride makes you think you’re not so bad

Similarly, if your body is short on vital humors like blood, you get filled up with a bunch of hot air as a substitute

We think of celestial sparks as inspiring the production of great works of art, not their consumption, but here celestial fire is meant to make would-be poets better appreciate the poetry that’s already written, and maybe not write at all
