It is believed that Indira is still worshipping Lord in this temple.  As an evidence of this fact, thunder falls through a hole in the tower above the sanctum sanctorum (Vimana) and goes around the Shivalinga.  Unbearable heat is experienced while opening the sanctum next day.  This happens once in a few years.  Scientists had proved that such an incident took place on the 10^th November, 1930.

Majority of the devotees throng the temple for mental peace and salvation.  Those mentally retarded come and stay here for 48 days, bathe in the Sangu Theertham, pray to Lord Veda Giriswarar and return fully cured.  This miracle is happening even now.  Diseases of any intense nature as Asthma, blood pressure and heart are cured by prayers to Lord.  They breathe the air with herbal effects and get cured. Devotees also come here seeking wedding, child boons too.

Two sages Poosha and Vruddha performed penance on Lord Shiva seeking Sharoopa status.  Lord modified their demand and granted the Sayujya status and promised elevation to Sharoopa later.  The sages refused to accept the offer and were adamant on their demand.  Angry Lord cursed them to become eagles.  Since then they are in this hill known as Shambu and Aadhi and are worshipping Lord with the Pakshi Theertha they had created.  It is believed that these eagles use to bathe in Rameswaram, eat in Kazhukundram and stay at Kasi each day.  The feeding of the eagles is going on for thousands of years, it is believed.  King Suraguru, to whom Lord granted darshan was instrumental for the creation of this sacred place, says the history.
