1. Aditi, mother of all devas, after giving birth to the devas had desire to have the Sarveshvara as her son. She expressed this to her husband Kashyapa who gave her the Ganesha Panchakshari mantra. She performed tapas and Ganesha appeared before her with 10 hands and his consorts Siddhi and Buddhi. Unable to bear his brilliance Aditi fainted. When she woke up, she prayed to the Lord to assume the form of a child and be her son. Ganesha was named Mahotkata in this avatara and later on destroyed demonesses like Viraja, Jrimbha and demons like Nishachara. He also saved Kashi from peril.
