Built of soapstone, granite and sandstone, the temple construction seems to follow the core tenets of typical north Indian temple architecture. The present building of the temple was constructed in the 18th century. Offering of water and flowers on the Shivalinga is one of the ways of expressing devotion to Lord Shiva. Worshipped in the form of a ‘shivlingam’, Mrityunjay Mahadev is said to be ‘swayambhu’ (self-manifested; not chiseled by hand). There is no other temple of Mahamrityunjaya in the world. Within the huge complex of Mahamrityunjaya Mahadev Temple are statues of several deities (देव विग्रह). The sanctum sanctorum of the temple is thousands of years old. There is also a Shivalinga inside the temple which is very important in the Hindu mythology. The temple building was built in the 18th century. Offering of water and flowers on the Shivalinga is one of the ways of offering devotion to the Lord Shiva. There are various smaller shrines inside the temple too which are thousands of years old again. Within the complex are several smaller temples of different deities. The idols of Ashtang Bhairav, Nageshwar Mahadev, Goddess Laxmi, Shani Dev and Lord Hanuman are worshipped here. The statue of Lord Hanuman was installed here by Goswami Tulsi Das. In all Shiva temples, the regular puja (Shraddha) ritual begins with Surya and ends with Bhairava. The temple complex also houses a ‘peepal’ tree and a religiously significant ‘kup’ (well). This historical well is known as Kalodak Kup. It is believed that thousands of years ago, Lord Dhanwantari had put in several medicinal herbs in the Kalodak Kup. Lord Dhanwantari is believed to be one of the 24 incarnations (अंशावतार) of Lord Vishnu. The devotees consider the water of the well having medicinal properties and healing powers with proven record of curing diseases of stomach and internal wounds. A devotee performing puja in Mahamrityunjaya Mahadev Temple believes to be cured from any kind of illness. Along with regular recitation of Maha Mrityunjay Mantra and sprinkling water from Dhanwantari Kup on oneself means that the devotee is protected by Lord Shiva’s blessings. The well is also called as Dhanwantari Kup. A large number of Brahmins can be seen here reciting and chanting Mahamrityunjaya Mantra.
