Recently we did beemaratha shanthi for my father at Thirukadaiyur. We were clueless on how to do that and to whom to contact.
Luckily I was able to look at the website tirukadavoor.com which provided a lot of details and also they arranged everything right from stay to homamams along with the food arrangements at a very resonable rate.
The site completely provided all the details of the historic place of tirujkadaiyur, and why should we do all the homams etc etc.
Its a very good information site on thirukadaiyur. It is a different site where all other websites had commercially focused where as this site was the only one which was providing more information on what I was looking for.
for further details please have a look at tirukadavoor.com
