Horary astrology is different from natal astrology . In the later, we need to have the birth details of the native, or the natal chart, which is not needed in Horary.
In Horary, a person A goes to another person B (who is of course the astrologer) with a question in mind.
And, based on the time and place, when and where, the question has being asked, the astrologer casts a chart. (This is called the Prashna Kundali).
He, then analyzes the chart, according to the methods of the doctrines, in order to give an answer to person A's question.
Now, suppose the person A himself is an adept in Horary. Can he himself cast the Prashna Kundali as per the time when the question arose in his mind? Or this is not allowed at all as per the doctrines of Horary? Or in other words, is the involvement of the two persons a must here?
