Hi, all.
Been meaning to post this for some months but finally remembered to get to it now!
I took the Tajika Prashna course here about 2.5 years ago. Since then I have about 140 Prashnas in my database that I have casted that have come to me or by other people asking me queries. Using the basic principles taught in that course (and some other aspects) I can confidently say that this system is about 90-95% accurate (which is Excellent for horoscopic astrology). I have even used the details of the Rasis from the rasi sutra course (such as direction, color, size of things) to find my lost suitcase as well as other lost objects which was very impressive.
I have also found the outer planets really color in details to the prashna if present but I do not use them for the prediction concretely.
It has taken about 2 years of practice to really get the hang of it. A lot of subtle details are in prashna that have to be practiced and seen and experienced. It is truly divination 101. You cannot force prashna, it happens when it happens.
The only limitation to tajika prashna is that it is basically for a year frame and of course you are not reading a natal chart, it is very specific, which is why perhaps it is so damn accurate. The south indian system, you can read for the whole life.
