Read the book thoroughly and start answering the questions the critics of astrology ask without understanding astrology through proper study and attack it blindly. This is the second of a series of monographs we have planned. If you get a horoscope of a person who has some doubt about his birth time and therefore the birth lagna, start verifying by asking about his siblings. The question should invariably be whether he is the first, middle, last or the only child of his mother. The stress here is on his being the eldest/middle/last or the only child of his monther. See how the rule of replication applies. We have given the simplest approach to settle it in the case of the youngest or the only child. In the monographs to follow we will show how one becomes, the middle child of his mother. - from Amzon
