Step 1: Understanding the Concept:
This question is from the poem 'Koel' by Puran Singh. The poet addresses the Koel (the Indian cuckoo), a bird whose song is deeply associated with spring, passion, and sometimes sorrow.
Step 2: Detailed Explanation:
The poet hears the Koel's high-pitched, piercing song and is struck by its intensity. The song sounds less like a happy melody and more like a cry of pain.
The poet personifies the bird and asks what tragedy has befallen it to make it sing in such a fiery, sorrowful way. He asks, "What lightning has fallen on you?" as a metaphor for a sudden disaster or immense grief. The question is directed at the Koel itself.
Step 3: Final Answer:
The poet wonders what lightning has fallen on the Koel.
