विवाहः
उत्पातग्रहणादूर्द्धं सप्ताहमखिलग्रहे ।नाखिले त्रिदिनं नेष्टं त्रिद्युस्पृक् च क्षयं तथा ॥ ४२३ ॥
In the full Narada Purana (Purva Bhaga) this is chapter 56, verse 423.
After a portent or an eclipse, avoid seven days when the eclipse is total. When it is not total, three days are not good. A tithi (moon day) that touches three days, and a lost one, are bad in the same way.
Simple meaning: Avoid seven days after a total eclipse and three after a partial one.
ग्रस्तास्ते त्रिदिनं पूर्वं पश्चाद्ग्रस्तोदयेऽथवा ।
Avoid days around an eclipse: three days, or seven if it falls at midnight.
मासान्ते पंच दिवसांस्त्यजेद्रिक्तां तथाष्टमीम् ।
Avoid the last five days of the month, certain bad moon days and some yoga times.
पौष्णभत्र्युत्तरामैत्रमरुच्चंद्रार्कपित्र्यभैः ।
Marry under Revati, the Uttaras, Anuradha, Svati, Mrigashira, Hasta, Magha or Mula.
