This temple situated above the tank near the Mahakaleshwar temple, enshrines a huge artistic sculpture of Ganesh, the son of Shiva. An idol of this size and beauty is rarely to be found. The middle of the temple is adorned by an idol of the pancha-mukhi (five faced) Hanuman. There is provision for learning of Sanskrit and Astrology in the temple
The Ganesh idol enshrined here is supposed to be swayambhu - born of itself. Worshippers throng to this temple because the deity here is traditionally known as Chintaharan Ganesh meaning "the assurer of freedom from worldly anxieties".
In the middle of the Ganesha temple lies a unique idol of loyalty and faith, that of the monkey-god, Hanuman. Nowhere else but in this temple Hanuman is depicted with five faces. Known as Panchamukhi (five-faced), Hanuman here symbolises courage, loyalty, devotion, strength, and righteousness. The Ganesha temple is also an important centre of learning. This reflects on the status of temples in ancient Vedic times, circa 1500 b.c. when houses of prayer were study centres too. This practice is prevalent even today in the South Indian temple complexes where idols are worshiped and religious teachings are imparted.
In Ujjain, the Bade Ganesha Ji Temple is an institute for teaching astrology and Sanskrit, an ancient Indian language considered the root of other Indian languages.
