जातकम् १
लयेशे धर्मगेजीवेष्टस्थे क्रूरेक्षिते जिताः ।लग्नाष्टमेशावष्टस्थौ भाब्दमायुःकरौ मतौ ॥ ११५ ॥
In the full Narada Purana (Purva Bhaga) this is chapter 55, verse 115.
The 8th lord may be in the 9th, with Jupiter in the 8th looked at by cruel planets. The lagna (rising sign) lord and the 8th lord may be in the 8th. That is held to risk a life of only 27 years. (Our text is unclear here: the years of the first rule, printed 'jitah'.)
Simple meaning: The lagna lord and 8th lord together in the 8th may shorten life to 27 years.
लग्नेऽशुभेज्यौ ग्लौदृष्टौ मृत्यौ कश्चन चाकृतिः ।
Some placements may shorten life to 22 years, others give long life.
शताब्दं गीष्पतौ कर्के कंटकस्थसितेज्ययोः ।
Jupiter in Cancer with these placements gives forty years. Another rule gives a hundred.
लग्ने शेष्टमगेष्टेशे तनुस्थे पंचवत्सरम् ।
Lagna and 8th lords swapped may shorten life to five years. Another placement gives fifty.
