Jataka Tattva · by Mahadeva
Chapter 6 · Mother and Home: the 4th House
चतुर्थविवेकः
चन्द्रे बलाढ्ये वा शुक्रे शुभयुतदृष्टे मातुर्दीर्घायुः ।
Say the Moon is strong. Or say Venus is joined or aspected by good planets. Then the mother lives long.
शुक्रे वा चन्द्रे शुभांशे केन्द्रे मातुर्दीर्घायुः ।
Say Venus or the Moon is in a good planet's navamsha (one-ninth part of a sign). It is in a kendra (corner house). Then the mother lives long.
सुखपांशेशांशपे केन्द्रे बलाढ्ये मातुर्दीर्घायुः ।
Take the 4th lord and the lord of its navamsha (one-ninth part of a sign). Now take the lord of that planet's navamsha. Say it is in a kendra…
सुखेशेऽङ्गे बलाढ्ये माता पतिव्रता ।
Say the 4th lord is in the lagna (rising sign) and strong. Then the mother is true to her husband.
