One-day child Ganesha, diverted himself in tormenting a cat, pulling her tail and rolling her up and down.
After a few minutes, he left the cat and went away. He never thought as to what he had done to the cat. He arrived at mount Kailash to meet his mother Parvati.
He found her suffering badly with wounds and dust. He then asked her about what had happened and she replied that he was only responsible for this situation.
Indeed she was the cat that was tormented by Ganesha. This story teaches us that all living beings are of divine importance.
If we injure any living being we injure God himself. Ganesha learned a lesson and we must also learn.
