One of the most intelligent branch of astrology is Horary Astrology. It has been practiced in India as Prashna Shashtra.
Many a times we come across people who have either lost their horoscopes or have lost their date/time of birth.
Prashna Shashtra is the process in which predictions are made according to a particular event of life or activity.
It is considered to be very precise. It is normally advisable to answer only query at a time if absolute accuracy is being expected.
