The Holy Bhawan houses the Sanctum Sanctorum – the Holy cave which is the ultimate destination of the yatries. Inside the Holy Cave the Goddess has revealed herself in the form of Holy Pindies manifesting Mata in her three forms Maha Kali, Maha Lakshmi and Mata Saraswati.
A pilgrim can get the first glimpse of Bhawan around 1.5 Kms before he actually reaches there. The first sight of the Holy Bhawan brings a sudden upsurge of energy and all the tiredness of the strenuous climb evaporates immediately as if by a magic wave of some mystic wand. The fact that the last 1.5 km of the Yatra are either level or gently sloping downwards is a big relief to those tired muscles. The feeling of having almost reached there fills the devotees with extra fervor and devotion. The last 1.5 kms. are then covered on wings, as it were, and in no time, the yatri reaches Bhawan.

Bhawan: Legend

It is believed that after leaving the Garbh Joon cave at Ardhkuwari, where Bhairon Nath had located her, Vaishnavi started ascending uphill till the time She reached the Holy Cave. Bhairon Nath who was pursuing Her, located her again inside the cave and started challenging her. So, finally the Goddess assumed Her Divine Form and severed the head of Bhairon Nath. There was so much power behind the blow of Her sword, that Bhairon Nath's head flew away and fell on another spur of the mountain about one & a half kilometer away, (the site of modern day Bhairon Temple) while his torso was left lying at the Mouth of the Holy Cave. The Goddess then immersed Herself into deep meditation inside the Sanctum Sanctorum where lies Her manifestation in the petrified form.
