Narada Purana (Jyotisha Selections) · by Vyasa
Chapter 8 · Marriage
विवाहः
प्रव्रज्या सूर्यपुत्रेण राहुणा मूलसंक्षयः ।केतुना संयुते चन्द्रे नित्यं कष्टं दरिद्रता ॥ ४५७ ॥
In the full Narada Purana (Purva Bhaga) this is chapter 56, verse 457.
With Saturn: one may leave home as a renunciant. With Rahu: the family root may suffer loss. With Ketu joined to the Moon: hardship and poverty may persist.
Simple meaning: The Moon with Saturn may bring renunciation, with Rahu loss at the root, with Ketu lasting hardship.
पापग्रहयुते चन्द्रे दंपत्योर्मरणं भवेत् ।
The Moon with bad planets may put life at risk. With good planets in a strong sign it helps.
दोषायनं भवेल्लग्नं दंपत्योः श्रेयसे सदा ।
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.
