Kalanirdesat Putra Yogas
Definition.-Jupiter should be in the 5th house and the lord of the 5th should join Venus-A.
Jupiter must also occupy the 9th from Lagna and Venus should be in the 9th from Jupiter, in conjunction with the lord of Lagna-B.
Results.–The native begets a son either in his 32nd, 33rd or 40th year.
Remarks.-These two yogas enable us to predict the probable period when one will have a son. If Jupiter is in the 5th and Venus is in conjunction with
the 5th lord, birth of a son in one’s 32nd or 33rd year can be predicted, provided the appropriate directional influences operate at the time the native reaches the above age, otherwise the yoga will not be valid.
Combination B says that Jupiter must be in the 9th from Lagna and Venus must be in the 9th from Jupiter. This is as good as saying that Venus must be
in the 5th from lagna. One born in this yoga will have a son in his 40th year, provided the appropriate Dasa and Bhukthi are current.
