In the full Narada Purana (Purva Bhaga) this is chapter 56, verse 523.
Leave out two years, and the days of the birth star and the birth lagna (rising sign). Then the wedding journey is good, even when Venus is set.
Simple meaning: Skip two years and the birth star and lagna days. The wedding journey is then good, even with Venus set.
आत्मानं संध्ययोर्हंति नास्ति गंडे विपर्ययः ।
A twilight birth may risk the child's own life. A Moola birth may risk the father-in-law's life.
तदंत्यपादजो नैव तथाश्लेषाद्यपादजः ।
A boy born in Jyeshtha's last quarter may put an elder sibling at risk. Mula's last quarter does not.
आरभ्योद्वाहदिवसात् षष्ठे वाप्यष्टमे दिने ।
