SIoka 31. The owners of the Sapthamamsa, or the 7th portions of Lagna and other hougas are in the case of an odd sign to be counted regularly from the lord thereof, while in the case of an even sign, they’are to be reckoned from the lord of the 7th house onwards.
This sloka gives the rule for finding out the lord of the Saptamamsa in the cases of odd and even signs. Thus, for example, the Sapthamamsas of Thula an odd sign will begin with Thula and end with Mesha while those of Vrischika, an even sign, will count from Vrishabha the 7th sign reckoned from Vrischika and close with Vrischika. The magnitude of each segment is 4 2/7.
Saptharnamsas are useful to ascertain the character or temperament of the native, he being cruelly disposed if born in a Krura Sapthamsa, or peaceful in nature if his birth happens in a Saumya Saptamamsa. This division is also utilised for seeking information about one’s brothers, etc.
