Yes, I have thought a lot about the nadis and how they give sidereal positions. I wish its something I could investigate more and actually read the leaves and have them dated. Are they translating them into the modern convention in india and do they even have rasis in them? who knows. But it should be investigated. I had a friend who went to nadis all over india. Very famous ones, unknown ones. He really was into seeing what they could do. He would take a 2 day train trip to visit one and then turn right around. The consistent thing with all his nadi readings was that they gave amazing details about his life upto the present, amazing details about his parents and family, but that most of the predictions for the future did not happen. So the past was accurate, the future accuracy was really poor. That makes me wonder, are many of these nadi's just working as psychics? Cause that is what I regularly experience with psychics, very accurate about past, but lost about the future.
There is something called the Jyotish Nadis. That is when the light opens up energetically in a person and they can do readings without astrology. Its still considered jyotish as its based on energy which is light and jyotish means light. So I wonder if these nadi readers are reading as Jyotish Nadis.
I have a couple questions about Tropical though.
When I use my Sidereal software with Lahiri, will the Vimshotarri dashas still be correct as we use Sidereal for nakshatras? Will the nakshatras still be correct? Or will they be wrong. I notice on vault of the heavens, the nakshatras/dashas are quite different.
But then if talking about the rashis, I use tropical?
Or where can I learn about this? I am starting the Parivartan course now.
Developing predictive astrology is all about developing the science of astrology. The science of astrology needs a lot of refining as do all sciences in the world, there is still a lot to learn, a lot of error to remove, a lot to discover even in these old sciences that languished in quality during the dark ages.
Using the word correct with any ayanamsa used for dasa calculation is a subjective question. An astrologer has to decide on which one to use based on their experience and testing. Vault of the heaven's uses a different ayanamsa for nakshatras than Lahiri. Lahiri puts the star chitra in the midle of chitra nakshatra. THe ayanamsa used on vaultoftheheavens puts the galacitc center in the middle of Mula nakshatra. The difference is over 3 degrees. If we put the galactic plane in the middle of mula instead of the galactic center itself, then we get an ayanamsa that is 26.5 minutes different than lahiri. WHa tis interesting is that lahiri later stated that he neglected an aspect of calculting his ayanamsa and that if he could do it all over again, he would add about 27 minutes to the lahiri ayanamsa, which would make it coincide with putting the galactic plane in the middle of Mula. ANyone who likes lahiri ayanamsa, I STRONGLY suggest using the ardhra galactic plane ayanamsa instead, which is my name for the ayanamsa where the galactic plane is in the middle of mula, which puts it at the beginning of ardra on the other side. I used this ayanamsa until end of 2006 with siderael astrology and I still think this ayanamsa has a lot of merit as I have talked about elsewhere.
