जातकम् १
नेष्टा योगाः शुभैर्दृष्टाः पापाः स्युर्नात्र संशयः ।मंदेऽस्ते मंदभांशेंगे निषेकेब्दत्रये जनिः ॥ ६४ ॥
In the full Narada Purana (Purva Bhaga) this is chapter 55, verse 64.
These unwanted combinations, seen by good planets ... are held to be bad. At conception, Saturn may be in the 7th. The lagna (rising sign) may be in Saturn's sign or navamsha (one-ninth part of a sign). Then the birth comes after three years. (Our text is unclear here: whether good planets' sight cancels these combinations.)
Simple meaning: Saturn in the 7th at conception, with the lagna in Saturn's sign, can delay birth three years.
द्वादशाब्दे शशिन्येवं सुतावपि विचिंतयेत् ॥ ६५ ॥
With the Moon placed this way, the wait is twelve years.
पितुः परोक्षे जन्मस्यादिन्दौ लग्नमपश्यति ॥ ६८ ॥
When the Moon does not see the lagna, the child is born while the father is away.
मध्याद्भ्रष्टेर्के विदेशस्थे जननेनारिजन्म वै ।
The Sun past the 10th, Saturn in the lagna, or Mars in the 7th can mean the father is away.
