संस्कारमुहूर्ताः
शाखेशे वा गुरौ शुक्रे महापातककृद्भवेत् ।स्वोच्चसंस्थे तदंशे वा स्वराशौ राशिगे गणे ॥ ३६३ ॥
In the full Narada Purana (Purva Bhaga) this is chapter 56, verse 363.
...that is, the shakhesha (lord of the person's Veda branch), Jupiter or Venus: he does great sins. Say one of them is in its own exaltation sign, or in that navamsha (one-ninth part of a sign). Or it is in its own sign... (Our text is unclear here: the words 'rashige gane'.)
Simple meaning: Branch lord, Jupiter or Venus in a bitter enemy's sign can lead the boy to great sins.
शाखेशे वा गुरौ शुक्रे केंद्रगे वा त्रिकोणगे ।
Branch lord, Jupiter or Venus in a good house brings wealth and Vedic learning.
परमोच्चगते जीवे शाखेशे वाथ वा सिते ।
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.
