Alfred, Lord Tennyson Quote

She sees the Best that glimmers thro' the Worst,
She feels the Sun is hid but for a night,
She spies the summer thro' the winter bud,
She tastes the fruit before the blossom falls,
She hears the lark within the songless egg,
She finds the fountain where they wail'd 'Mirage'!

From The Ancient Sage (1885), lines 72-77
