Legend

The childless king, Bhima of Koudinyapur and his wife met the sage Vishwamitra while they had come to forest for penance. Vishwamitra gave the king a mantra  Ekashar Gajana Mantrato chant and thus his son and heir, prince Rukmaganda was born. Rukmaganda grew up into a beautiful young prince.

One day, on a hunting trip Rukmaganda stopped at the hermitage of Rishi Vachaknavi. The Rishi's wife, Mukunda, fell in love at the sight of the handsome prince and asked him to fulfill her desires. The virtuous prince flatly refused and left the ashram. Mukunda became very lovesick. Knowing her plight, King Indra took the form of Rukmaganda and made love to her. Mukunda became pregnant and gave birth to a son Gritsamada.

In time, when Gritsamada learned of the circumstances of his birth, he cursed his mother to become the unattactive, thorny berry-bearing "Bhor" plant. Mukunda in turn cursed Gritsamada, that a cruel rakshas (demon) will be born from him. Suddenly they both heard a heavenly voice saying, "Gritsamada is the son of Indra", leaving them both shocked, but too late to alter their respective curses. Mukunda was transformed into the Bhor plant. Gritsamada, ashamed and penitent, retreated to the Pushpak forest where he prayed for a reprieve to Lord Ganesh (Ganapati).

Lord Ganesha was pleased by Gritsamada's penance and offered him a boon that he will bear a son who would not be defeated by anybody other than Shankara (Shiva). Gritsamada asks Ganesh to bless the forest, so that any devotees who pray here will be successful, and also urged Ganesha to stay there permanently and asked for knowledge of Brahma. Gritsamada built a temple there and the Ganesha idol installed there is called Varadavinayaka. Today the forest is known as Bhadraka.

It is said that if the coconut received as prasad during Maghi Chaturthi is consumed, one will be blessed with a son. Hence the temple is especially full with devotees during Maghi Utsav.
