Quote #1
The blissful cloud of summer-indolence (16)
The speaker associates the pleasures of laziness with elements of nature, like clouds on a summer's day. It isn't the last time he'll refer to the sky when waxing poetic about how relaxed and untaxed he feels. For him, having the luxury to stare at the clouds is worth giving up many of life's more extreme pleasures.
Quote #2
My soul had been a lawn besprinkled o'er
With flowers, and stirring shades, and baffled beams: (42-43)
Nature has become entwined with the speaker's soul. He uses a metaphor to liken his relaxed spirit to a lawn sprinkled with flowers, spots of shade, and sunbeams. Even if he isn't physically there, he can dream of a lovely day during one of his lazy reveries. And the aspects of nature he chooses to represent his soul? They all belong to a warm summer day.
Quote #3
The morn was clouded, but no shower fell,
Tho' in her lids hung the sweet tears of May; (44-45)
There's a threat of rain, but it looks like the grass is going to stay dry for our dear speaker. The clouds only serve to provide a pleasant shade for him to enjoy. Notice here that Keats personifies nature. She wants to cry, but isn't going to. That doesn't mean she's sad, though. The tears are described as "sweet" and, if we know anything about the poem, we know that the elements of nature Keats uses are associated with enjoyment.
