Please do not waste your time and money with this particular nadi astrologer. I had been there and **he** asked me 100 questions before acting as if he found the correct leaf for me! Then he summarised my sayings as my "past" as per nadi!!!!
I am doing research on Nadi and other forms of astrology . However , nadi is so much hyped by some people.
BTB, the said nadi family is in Vaideeshwaram (behind the temple). You can ask anybody in Vaideeshwaram and they will show you this "shop". I paid Rs 4000 and got a recorded cassette as well. You better try somewhere else and even if you want to try in the same place, go for cheaper options (I guess 500 Rs, so that at least your loss is less. I will publish all the details in my blog soon. but please come out from the hype fever of nadi..
Vaideeshwaram is about 90 Kms from Pondicherry and 20 kms from Chidambaram. There are direct buses from Chennai also.. Temple is good but you can see people cheating you every minute, including the priests unless you are careful.
