Ganesh advice the sage that if he want forgiveness for what he has done, then he must release the Ganga from Shiva's hair. He tell the sage that let the waters flow down to earth, and then he must take a bath in the river Ganga. If he can do this, then he will be purified and all his sins will be washed away. Later the sage used his spiritual power to bring the water down to earth. When the Ganga was flowing properly, he bathed in it and became purified.
