Chapter 7 · Samskara Muhurtas
संस्कारमुहूर्ताः
विना वसंतऋतुना कृष्णपक्षे गलग्रहे ।अनध्याये विष्टिषष्ठ्योर्न तु संस्कारमर्हति ॥ ३७८ ॥
In the full Narada Purana (Purva Bhaga) this is chapter 56, verse 378.
Do the rite in spring. Not in the dark fortnight. Not on a galagraha (a bad day) or an anadhyaya (day when study stops). Not in vishti (bad half of a moon day) or on the 6th. The samskara (life rite) is not fit then.
Simple meaning: Do the rite in spring. Avoid the dark half, bad days, study holidays, bad half-days and the 6th.
त्रयोदश्यादिचत्वारि सप्तम्यादिदिनत्रयम् ।
The 13th to the 1st, the 7th to 9th, and the 4th are the eight bad days.
क्षुरिकाबंधनं वक्ष्ये नृपाणां प्राक्करग्रहात् ।
Kings tie on the dagger before marriage, in marriage months and the bright half.
जीवे शुक्रे च भूपुत्रे चंद्रताराबलान्विते ।
Jupiter, Venus and Mars not set, Moon and star strength, thread-rite days, and any day but Tuesday.
