Astrological predictions can also be done accurately using the Prashna / question technique.
The basic reason for failed astrological predictions is undoubtedly the non-availability of an accurate birth horoscope, often due to inaccurate time of birth.

Even where an accurate birth chart is available, there are many areas where the need to know the immediate future or for solving immediate problems and anxieties of the querist, can only be forecast using a Prashna chart.  

Bharat Samachar charges US $ 10 per Prashna.
