So many natural watercourses whose divinity and sanctity dates back to vedic ages, Tirumala provides an ethereal appeal to the devotees. In one way or the other this torrential water course are connected with the legendary characters in the puranas. Tumburu teertham is not an exception to this common rule. It holds the story of Thumburu, a gandharva who cursed his wife for her laziness. As per this, the lady became a toad who had to survive in the pond till sage Augusthya came there with his disciples. While the great sage described the divinity of the pond to his disciples, the toad regained her Gandharva form and hence this teertham began to be called as Tumburu teertham.
