Add the correct figures for the lords of the 5th and the 1st bhavas, and find out the Rasi and the amsa the sum represents. When Jupiter passes through this and its triangular positions, there is a possibility of a son being born. Again, take the sum of the figures for Jupiter, the Moon and the Sun, and ascertain the Rasi and the Navamsas the sum represents. The number of the Navamsas obtained give the number of issues of the person concerned. Two more alternative methods for ascertaining this number are: (1) add the figures of the lords of the 5th, the 9th and the 4th bhavas and ascertain the number of past Navamsas in the Rasi found; (2) add the figures of the planets if any in the 5th, the 9th and the 4th bhavas. The number of children will be the number of elapsed Navamsas in the Rasi found.
