Gritsamada's boon in the Bhadraka forest
Bhima, king of Kaundinyapur, and his queen are childless. In the forest they meet the sage Vishvamitra, who gives them a Ganesha mantra, and a son, Rukmangada, is born to them.
Rukmangada grows up and one day comes to the hermitage of the sage Vachaknavi. The sage's wife, Mukunda, desires him, and he refuses her. Indra then takes on Rukmangada's form, goes to Mukunda, and fathers a son by her. The child is Gritsamada.
When Gritsamada grows up and learns how he was born, he curses his mother to become a thorny plant. She curses him in return: a demon will be born from him. A voice from heaven declares that Gritsamada is Indra's son, but the curses have already been spoken and cannot be taken back.
Gritsamada goes to the Pushpaka forest and performs penance to Ganesha. Ganesha appears and grants him a son who can be defeated only by Shiva. Gritsamada asks Ganesha to remain in that forest, and Ganesha agrees. Gritsamada builds a temple there, and the forest becomes known as Bhadraka.
The god who stays to grant what was asked is Varada Vinayaka, Ganesha the giver of boons, and the Mahad tradition identifies its temple with the shrine Gritsamada built.
