*(Test it and see if it fits: With Mars in the 6th, there are two uncles (father's brothers), and with Mercury in the 8th, there are two aunts (mother's sisters).)*
Lal Kitab is not just about predicting the future; it can accurately map out a person's entire family tree just by looking at planetary placements.
Dr. Sharma challenges skeptics to test ("aazma ke dekhe") these two highly specific rules: 1. Mars in the 6th House: Mars represents brothers. In the 6th house, it specifically indicates that the person's father will have exactly two brothers (the person will have two "Chachas"). 2. Mercury in the 8th House: Mercury represents sisters/aunts. In the 8th house, it indicates that the person's mother will have exactly two sisters (the person will have two "Mausis").
This level of genetic accuracy is what makes Lal Kitab the most mystical branch of astrology.
