Chapter 8 · Marriage
विवाहः
दोषायनं भवेल्लग्नं दंपत्योः श्रेयसे सदा ।स्वोच्चगो वा स्वर्क्षगो वा मित्रक्षेत्रगतोऽपि वा ॥ ४५९ ॥
In the full Narada Purana (Purva Bhaga) this is chapter 56, verse 459.
that lagna (rising sign) has its faults go away, and it is always for the good of the couple. The Moon may be in its own high sign, in its own sign, or in a friend's sign. (Our text is unclear here: the word for 'faults go away'.)
Simple meaning: With good planets and a strong Moon, the lagna's faults go and it favours the couple.
पापग्रहयुतश्चंद्रः करोति मरणं तयोः ।
The Moon with bad planets may put the couple's life at risk. The 8th from their lagna and sign comes next.
यदि लग्नगतः सोपि दंपत्योर्मरणप्रदः ।
If the 8th sign from theirs rises at the wedding, it may put the couple's life at risk.
लग्नं विवर्जयेद्यत्नात्तदंशांशतदीश्वराम् ।
Avoid that lagna, its navamsha and their lords. The 12th from their lagna or sign rising is next.
