There
are in our existence spots of time,
That with distinct pre-eminence retain
A renovating virtue, whence depressed
By
false opinion and contentious thought,
Or aught of heavier or more deadly weight,
In trivial occupations, and the round
Of
ordinary intercourse, our minds
Are nourished and invisibly repaired;
A
virtue, by which pleasure is enhanced,
That
penetrates, enables us to mount,
When high, more high, and lifts us up
when fallen.
