He wiped the blood with his clothes and torn them for making bandages for the dog. The heavenly angel said to himself, Shri Krishna is really a kind king. He resumed his true form and praised Shri Krishna for his kindness. The moral of the story is that we should try to be kind, like Shri Krishna. We should help everyone, whether they are humans, animals, birds, or any other living being, who is suffering.
Nobody likes pain or suffering.
We should be helpful.
