From now on I will weep and fret in the evenings because I saw absolutely no effect in my morning lamentations.

This powerful couplet captures the poet's sense of dramatic, yet temporary, sorrow. He declares that he will weep profusely this evening, making a grand spectacle of his grief. However, he immediately counters this declaration by saying he hasn't witnessed the lasting, permanent impact in the stream of dawn. It's a profound reflection on the difference between surface-level emotional outburst and deep, transformative reality.
