संस्कारमुहूर्ताः
वारौ तु मध्यमौ चैव व्रतेऽन्यौ निंदितौ मतौ ।त्रिधा विभज्य दिवसं तत्रादौ कर्म दैविकम् ॥ ३६० ॥
In the full Narada Purana (Purva Bhaga) this is chapter 56, verse 360.
...those two days are middling. The other two are held bad for the vrata (vow rite). Divide the day into three. In the first part, do the rites for the gods.
Simple meaning: Moon and Sun days are middling. Mars and Saturn days are bad. Do god rites in the first third of the day.
द्वितीये मानुषं कार्यं तृतीयेंशे च पैतृकम् ।
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.
