संस्कारमुहूर्ताः
परमोच्चगते जीवे शाखेशे वाथ वा सिते ।व्रती विशुद्धे निधने वेदशास्त्रविशारदः ॥ ३६५ ॥
In the full Narada Purana (Purva Bhaga) this is chapter 56, verse 365.
Say Jupiter is at its deepest uchcha (high point). Or the shakhesha (lord of the person's Veda branch) or Venus is there. The 8th house is clean. Then the initiated boy is expert in the Veda and its sciences.
Simple meaning: With Jupiter or Venus very strong and a clean 8th house, the boy masters the scriptures.
स्वाधिमित्रगृहस्थे वा तस्योच्चस्थे तदंशगे ।
Branch lord, Jupiter or Venus in a great friend's sign brings learning and wealth.
शाखाधिपतिवारश्च शाखाधिपबलं शिशोः ।
The branch lord's day, his strength and his rising sign are rarely found together.
श्रवणादिनि नक्षत्रे कर्कांशस्थे निशाकरे ।
Moon in Shravana or Punarvasu, in a Cancer navamsha, brings learning, wealth and grain.
