One of reader has an interesting information to share, he also happens to be the direct dissident of Ogur Srinivasa Rao, the devotee who bought the bells. Thanks, Raghu sir, much appreciated!
A group of workers were breaking down stones on a hill called Sampath Giri in Polur village in Thiruvanamalai dist. of Tamil Nadu. Workers were busy doing their job. One of the workers sphear hit a rock, and for everyone’s shock it started bleeding. They were frightened and left for the day. One the same night, Lord Narasimhar showed in one of the devotees dream. Lord Narasimhar said that he has come one his own to sampathgiri as shantha Murty. Next day, the devotee informed this to the villagers. All villagers came to see the idol. They were all shocked to see the lord bleed. All the villagers came together and built a Maha Mantapam for the lord Narasimhar. They worshiped the lord with great bakthi and shraddha. A temple was built atop of the hill for lord Narasimhar. Later people installed Lakshmi- the consort of Lord Narasimhar.
Lord Narasimhar invited two brothers namely kolasthiyar Rushi and Pulasthiyar Rushis to this temple. These two rushis were ardent devotees of Lord Narasimhar. These two sages did penance to lord Narasimhar and the lord was impressed by their devotions. Impressed by their bakthi, lord gave them a mango. A fight broke up between the two brothers as who would take the mango. In the spur of the moment, Pulasthiya rushi chopped his younger brother Kolasthiyar’s hands. Even after losing both hands Sage Kolasthiyar continued to worship the lord with great devotion. He took bath at ''seyyar'' (3kms from polur) for 48 days (i.e. 3 mandalams) and circled the SampathGiri. After 48th day, Kolasthiyar's hands reappeared magically! This not only surprised the sage, but also others present. It was Lord's plan that Ustavmurthy should be installed by Kolasthiyar rushi. Lord came in Kolasthiyar rushi's dream and gave direction as where the uthsava murthy was. It was in a place called Karapoondi in seyar. The sage went to look for the utsavamurthy with the direction given by the lord. He found the uthsava Murthy and established a temple i.e. down the hill.
Later, a king from vijayanagar dynasty expanded the temple. The king built a temple for vengopala swamy and his consorts Rukmini and Staybama. They also carved 840 steps on the rocks for the devotees to reach the Lord Lakshmi Narasimhar temple. Even today the devotees use these steps. Some 160-180 years back lord again appeared in one of the devotees dream and said that he needs bells for the temples. The devotee, Srinivasa Rao later bought bells for the temples. Even today, one can find this big, majestic bell at both temples and can also see the painting of Srinivasa Rao on the wall.
May the lord Narasimhar bless us all!
