जातकम् १
रवींदुयुक्ते सिंहेंगे माहेयार्किनिरीक्षिते ।नेत्रहीना मिश्रखेटैर्दृष्टे बुद्बुदलोचनाः ।व्ययेजो वामनयनं दक्षं सूर्यो विनाशयेत् ॥ ६३ ॥
In the full Narada Purana (Purva Bhaga) this is chapter 55, verse 63.
The Sun and the Moon are joined in Leo in the lagna (rising sign). Mars and Saturn see them. The child is blind. Seen by mixed planets: bubble-like eyes. In the 12th, the Moon spoils the left eye and the Sun the right eye.
Simple meaning: The Sun and Moon in Leo in the lagna, seen by Mars and Saturn, can give blindness.
Classical view, not medical advice.
नेष्टा योगाः शुभैर्दृष्टाः पापाः स्युर्नात्र संशयः ।
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.
