Today their arrival is expected once again, and we have turned autumn into spring.

This couplet beautifully captures the transformative power of love and anticipation. Just the rumor or impending arrival of the beloved is enough to turn the poet's withered, desolate world into a blossoming garden. Here, 'autumn' stands for emotional sorrow and loneliness, which dissolves completely into the vibrancy of 'spring' at the mere thought of reunion.
