Pl do not make observations saying it is bluff without knowing the background.
The basis for Nadi josyam is that there are only finite num of permutations/combinations that a person can live in this world. So all the permutations & combinations comes to around 8 lakh different lives (not sure if I got this # correct) as per our ancients. Hence, many of our lives will be similar, similar # of siblings, kids, etc… similar problems, jobs, etc… which is quite true if you take the time to analyze the lives…
so based on this, there is a detailed map of these 8 lakh lives in the Nadi grantham leafs which these astrologers use to predict the past & future…
have you ever wondered how anyone can predict some one’s life – is there any logic ? – so you can see how smart our ancients were, if all our lives are similar, then we can easily predict the past, current & future…
lets understand our glorious heritage properly before commenting on it… our ancestor brahmin rishis were truly geniuses…
