Sri Bhuvarahaswamy temple Srimushnam a Divya desam-Adhishtanam of the 37 th Sankaracharya of the Kamakoti peetam Sri Vidhyaghanendra Saraswathi(758-788 AD)

Very close to Vriddachalam is Srimushnam a place where there is a divyadesam temple dedicated to Varaha avataram of Sri Vishnu. The temple is famous for being a swayumbhu murthy with the reputation of saving vehicles. I saw a lot of repaired vehicles being parked here for puja before being put into use.
How to reach:
Srimushnam is about 20 kms from Vriddachalam . Proceed on the road to Pennadam and Andimadam take a left turn at the first bifurcation and at a place called vannankudikadu take a left to Srimushnam, the route is easy to find.

You can also comr from Sethiathope near neyveli on NH 45C and take a right at thimmasamudram to reach Srimushnam
Legends of the temple:
The lord here is swayambhu and is formed from a single large black stone saligrama. The lord is facing west and his face (Boar) is turned upwards and facing south.
His consort ambujavalli thayar was born nearby in Neyveli and as per her wishes the utsava murthy is having a human face.
The swami here is swayam yukta in the idol, the pond behind the temple in front of the Shiva temple

the holy pond

Swayam Yuktha perumal is in the pond also

and also in the huge Banyan tree in front of the pond.

  Please do not miss these during your visit
The is also a story that says that the moorthy is actually a meteorite. The bhattar was explaining that there is a huge crater behind the perumal statue and the saligramam mala adorning the perumal also was svayam vyakta. The saligramam are all covered with chakra and conch symbols it seems

The bhattar sells a unique ladoo made of the roots of the grass and lots of sugar tastes as rava laddu. It costs 10 rs each

The temple was under patronage of the Hoysala kings and has exquisite stone sculptures which reverberate musically . The pillars are a marvel carved from a single block of granite and having 3 different sections with many sculptures
