An apparently impossible scene in poetry should not automatically be read as factual reportage. But neither should every impossible claim be excused merely because it appears in verse.
Question 1: Is the sentence reporting an event or imaginatively intensifying a characteristic?
Question 2: Does a qualifier such as yakādu or law, or a coherent image, support the expression?
Question 3: What quality becomes more vivid for the listener?
These three inquiries help separate classification of exaggeration from evaluation of its rhetorical acceptability.
