| Quote #1 For my first twenty years, since yesterday, (line 1) |
One of the main themes of the poem is how the speaker's sense of reality is twisted around by the calamity that has befallen him: a day without his lover. But he has not gone crazy, because he can still compare his sense of time with the "real," external time.
| Quote #2 Tears drown'd one hundred (line 5) |
Although the poem is technically about love, the speaker's ego is always at the center. He is a larger-than-life figure whose tears can "drown" a century. What he means, of course, is that he has spent an entire century crying. Also, reality gets more and more bent out of shape throughout the poem, as time expands.
| Quote #3 Or not divide (line 7) |
Our best guess is that "or not divide" means, "nor could I divide." Division is a pun because it is both a spiritual activity (division of the self) and a mathematical procedure, a kind of "computation".
