In the full Narada Purana (Purva Bhaga) this is chapter 56, verse 380.
I will tell of the kshurika-bandhana (tying on the dagger) for kings, before marriage. Do it in the months told for marriage, in the bright fortnight, when the planets are not set...
Simple meaning: 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.
नचेन्नवांशके कर्तुरष्टमोदयवर्जिते ।
Avoid a rising sign 8th from the birth sign. Keep the 8th clean. Keep the Moon out of 6, 8, 12.
आयामार्द्धाग्रविस्तारप्रमाणेनैवच्छेदयत् ।
