The reason why lots of devotees come to this temple is due to the presence of special Sri Yantra (a symbol of Sakthi) referentially consecrated in the sanctum - garbagriha. The Sri yantra being powerful, the belief is  when a devotee makes a wish on the temple premises with  trust in the powers of goddess here, his or her  wish will be fulfilled much to the satisfaction  of the devotee;  hence the sanctified place imparts positivity on the devotees. Yet another feature of this temple is people afflicted with  Kala-sarpa-dosha - as per their horoscope - will be freed from the  ill- effects if they worship God Shiva here who goes by the name of   Kunteshwar Mahadev.
