Narada Purana (Jyotisha Selections) · by Vyasa
Chapter 8 · Marriage
विवाहः
तल्लग्नं वर्जयेद्यत्नाज्जीवशुक्रसमन्वितम् ।उच्चगे नीचगे वापि मित्रभे शत्रुराशिगे ॥ ४५३ ॥
In the full Narada Purana (Purva Bhaga) this is chapter 56, verse 453.
Drop that lagna (rising sign) carefully, even if Jupiter and Venus are with it. It makes no difference if the Moon is in its uchcha (high point) or its nicha (low point). Nor if it is in a friend's sign or an enemy's sign.
Simple meaning: Drop such a lagna even with Jupiter and Venus, and whatever the Moon's sign.
अपि सर्वगुणोपेतं दंपत्योर्निधनप्रदम् ।
It may put the couple's life at risk. The Moon joined by any planet is the Samgraha fault.
तस्मिन्संग्रहदोषे तु विवाहं नैव कारयेत् ।
Do not marry in the Samgraha fault. The Sun with the Moon may bring poverty.
कुजेन मरणं व्याधिः सौम्येन त्वनपत्यता ।
The Moon with Mars may risk life or bring illness, Mercury may deny children, Jupiter bad luck, Venus a co-wife.
