When I asked a couple of different ragis and gyanis, they told me not to believe the stories that some make up to answer this question without having to do research about it.
For example, in Bhagat Farid's saloks, when he is talking about a crow, he is not literally talking about a crow as depicted in pictures, he is talking about Kaam, Krodh , Lobh, Moh, and Ahunkar.
But some just tell of a story where Bhagat Farid Ji saw a crow and wrote the saloks telling the crow to leave him alone, when he was telling Kaam, Krodh, etc to leave him alone.
That is what I mean.
