hello Ravi,
I heard it is somewhere near Chennai, some temples have the very rare and sacred leaves , which contains the details of all human lives..
however it is for an individual,
it was something..
a log book, maintained, for all human lives with their karmas, and in an accident by flood, the PALI leaves were washed away, and it is said that now only 60-70% of them are available and with temple trusts, some of which are in south india.
The above which i said, is theonly thing i can recollect as of now,
maybe i am wrong.
Please correct the same, and please update with more info on this too.
Thanks
