Unmatta Bhairava is one of the Ashta Bhairavas and there is miraculous
and powerful Unmatta Bhairava temple near the Amarnath Cave. In the south of
Amarnath cave, at a distance of about half-a-kilometer, there is a sacred
shrine of Unmatta Bhairava. It is said that Adi Shankaracharya himself
established this shrine and the murti (vigraha or idol).
Unmatta Bhairava blesses a devotee who reaches the place walking
without any footwear. A besan ladoo mixed with honey and liquor is place on
the protruding tongue of the Bhairav murti. As soon as the sweet is place on
the tongue of Bhairava it moves back in the mouth and the offering is
swallowed. Soon the tongue returns and comes out of the mouth of the image. The
devotee finds a few drops of liquor on the tongue. The devotee collects them as
the prasada of Unmatta Bhairava and is blessed by the deity. With the blessing
of the deity, all the wishes of the devotee is fulfilled.
Behind the Unmatta Bhairava shrine are hot water springs.
They have the capacity to cure a number of diseases, particularly skin
diseases.
This Bhairava is known as remover of diseases and giver of
progeny to his devotees. It is said that when a devotee, closing his eyes, sits
before the Bhairava image, with certain wish or desire in his mind the reply
instantly flashes before his mind’s eye.
