Other things make this a special temple.
Yes, indeed, the Shivling of the temple we are talking about today itself keeps on changing its color. The name of this temple is "Mendhak Mandir", it is a pagoda it was built by Maharaja Baksh Singh of the Chahamana dynasty in the 11th century. At that time the entire area around this temple was a worshiper of Lord Shiva and this area was considered to belong to the Shiva sect. The architectural art of this temple is not determined by any common man, but its map was made by the then-great Tantrik Kapila according to Manduk Tantra.
Along with this, the artifacts of Shiva Sadhana are also present on the walls of this temple. The Shivling of this temple was brought from the holy river Narmada, hence the Shivling in this temple is known as "Narmadeshwar Mahadev". This Shivling named Narmadeshwar Mahadev keeps changing its color by itself. This is the specialty of the Shivling of this temple, as well as in this temple you find the statue of Nandi not sitting like in other temples but standing. Presently this temple remains a symbol of the historical dignity of the whole area.
