संस्कारमुहूर्ताः
द्वितीये मानुषं कार्यं तृतीयेंशे च पैतृकम् ।स्वनीचगे तदंशे वा स्वारिभे वा तदंशके ॥ ३६१ ॥
In the full Narada Purana (Purva Bhaga) this is chapter 56, verse 361.
In the second part, do the rites for people. In the third part, do the rites for the pitri (ancestors). Say the planet is in its own debility sign, or in that navamsha (one-ninth part of a sign). Or it is in an enemy's sign, or in that navamsha.
Simple meaning: God rites first, people rites second, ancestor rites third. A planet in a weak or enemy sign starts a bad case.
गुरुशिखिनोश्च शाखेशे कलाशीलविवर्जितः ।
Jupiter or the branch lord in a weak or enemy sign leaves the boy without skills and good conduct.
शाखेशे वा गुरौ शुक्रे महापातककृद्भवेत् ।
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.
