This teachings written by scholar shri Ram Krishan Goel, now residing in Gurgoen. This Nadi system where Ascendent is considered equally very important. Now for us he has produced the series to understand the basics and naunces of original Nadi Astrology. This particular material is cover under his copyright as wherever applicable.
[Vijay Goel] I find it is expansion of R G Rao's nandi nadi concept with ascendent. All nadis has same basic but little bit differet in applications. Much of the basic content is taken from "Core of Nadi Astrology" of Late RG Rao.
