Trimbakeshwar Jyotirling is on the banks of Gautami near Nasik in Maharashtra. Of the twelve JyotirLingas of Lord Shankara, the tenth one is known as Tryambakeshwara.
Gautam Muni resided on the Brahmagiri hill with his wife Ahilya. By virtue of his devotion, the sage received from Varuna, a bottomless pit from which he received an inexhaustible supply of grains and food. The other rishis, jealous of his fortune, arranged for a cow to enter his granary and caused it to die as Gowtam Rishi attempted to ward it off with a bunch of Darbha grass. Gautam Rishi, therefore, worshipped Lord Shiva to bring the Ganga down to his hermitage to purify the premises. Pleased with devotion, Shiva requested Ganga to flow down and make Sage Gautam pure. After that Ganga flowed down. Lord Shiva told Ganga to stay there eternally for the good of everyone. All the Gods started singing the praises of Gautam Rishi, Ganga and Lord Shiva. On the request of all the Gods, Lord Shiva resided by the river Gautami by the name Trimbakeshwar (one of the Jyotirlingas). Hindus believe that Trimbak Jyotirlinga is one, which fulfills everyone’s desires. It emancipates all from their sins and miseries. Another popular legend behind Trimbakeshwar Temple is the legend of Lingodbhava manifestation of Shiva. It says once Brahma and Vishnu searched in vain to discover the origin of Shiva who manifested himself as a cosmic column of fire. Brahma lied that he had seen the top of the column of fire and was hence cursed that he would not be worshipped on earth. In turn Brahma cursed Shiva that he would be pushed underground. Accordingly, Shiva came down under the Brahmagiri hill in the form of Tryambakeshwar. Trimbakeshwar Temple is the only place where Shivlinga is not out but it’s inside the floor. Some scholars say that Goddess Parvati also came down along Lord Shiva and Ganga. The place is therefore called Tryambakeshwa. Others believe that the place is so called because of the presence of three Shivlinga of Brahma, Vishnu and Mahesh. The Shivlinga of Lord Mahesh has always-flowing water among the three Shivlingas.
