जातकम् १
भासमाने सरे मार्गे स्थिरे स्वर्क्षांशगे गृहे ।त्रिकोणगेज आरार्क्योरस्ते वा सृज्यतेऽम्बया ॥ ८० ॥
In the full Narada Purana (Purva Bhaga) this is chapter 55, verse 80.
If the sign is movable, the birth is on a road. If it is fixed, or in its own navamsha (one-ninth part of a sign), it is at home. Mars and Saturn may be in a trikona (luck house) or the 7th from the Moon. Then the mother leaves the child. (Our text is unclear here: the first word, and 'srjyate', read as 'is left'.)
Simple meaning: A movable sign means birth on a road, a fixed one at home. Mars and Saturn can mean the mother leaves.
गुरुदृष्टे तु दीर्घायुः परं च प्राप्यते पुनः ।
Jupiter's look protects the left child. A hurt Moon rising with Mars in the 7th may risk its life.
पितृमातृगृहे जन्म तदधीशबलान्मुने ।
Strong parents' lords point to birth in their home. A good planet in its low sign points to a hut.
एतल्लक्षणसंपन्ना प्रसूतिर्विजने तदा ।
The birth may be in a lonely spot. A Moon in the 4th under Saturn's touch points to a dark place.
