Anne Brontë said this quote

To regret the exchange of earthly pleasures for the joys of Heaven, is as if the grovelling caterpillar should lament that it must one day quit the nibbled leaf to soar aloft and flutter through the air, roving at will from flower to flower, sipping sweet honey from their cups, or basking in their sunny petals. If these little creatures knew how great a change awaited them, no doubt they would regret it; but would not all such sorrow be misplaced?
